Abstract:
A method and a device for indication of leakage in a liquid system, includes liquid lines and a liquid filter that consists of a non-transparent upper portion (3) having flow paths (5, 6) for the supply of liquid to the filter and discharge of liquid from the filter, and a transparent lower portion (4) having a transparent casing (7) and a filter unit (11) positioned inside the casing (7). It is significant for the device that an indicating channel (27) is connected to the inlet flow path (5), the indicating channel (27) extending below the upper portion (3) and having an outlet opening (31) that emerges in the lower portion (4) and being arranged to discharge supplied liquid so as to be visible to a person's eye and also visually indicate gas bubbles/air bubbles (39) that possibly are present.
Abstract:
A fluid filter assembly having a relief valve for visually indicating the life of a filter element. The fluid filter assembly of the present invention provides a vertical, transparent housing having a fluid inlet for communicating a fluid into the housing and a fluid outlet for communicating fluid downstream of said housing. A filter element is disposed within the housing between the fluid inlet and the fluid outlet for filtering the fluid. In the preferred embodiment, a frusto-conical divider is connected to the top of the filter element and extends downward adjacent a bottom portion of the filter element wherein the fluid from the inlet rises between the filter element and the inside of the divider and between the outside of the divider and an inside surface of the housing. A relief valve is provided in the top of the filter element and is in communication with the unfiltered and filtered side of the filter element. The relief valve opens at a predetermined pressure level across the filter element thereby raising the fluid level and providing a visual indicator that the filter element needs replacement
Abstract:
A drain assembly for a fluid filter includes a female valve portion unitary with an end wall of a collection bowl, and having a socket with a cylindrical sidewall and an inner end wall. The end wall includes a plug, and a vent opening radially outward from the plug. A drain opening is provided in the end wall radially outward from the socket. An annular sealing surface is provided radially outward from the drain opening. A threaded sleeve is provided radially outward from the annular sealing surface. A male valve portion is received in the female valve portion, and includes a valve body and valve seal. The valve seal is received in the socket and includes a cylindrical sidewall defining a vent passage, and an inner end with a vent opening to the vent passage. An annular sealing surface is provided radially outward from the sidewall of the valve seal. The sealing surface on the valve body is sealable against the sealing surface on the bowl end wall, and has an outer diameter sufficient to cover the drain opening in the bowl end wall. The valve body has a drain opening radially outward from the valve seal. The valve body includes a threaded sleeve radially outward from the annular drain opening in the valve body. The threaded sleeve of the valve body cooperates with the threaded sleeve of the female valve portion to enable the male valve portion to be screwed into and outwardly from the female valve portion.
Abstract:
A fuel filter assembly that provides a constant level of least restricted fuel flow through the fuel filter assembly during the useful life of the filter media by utilizing the least possible amount of filter media to provide the least possible pressure differential over the filter media while also providing a constant level of fuel additive by exposing an amount proportional to the filter media required for the least possible restricted fuel flow. The fuel filter assembly utilizes a vertically upward housing that houses a filter media and a fuel additive. The fuel level slowly rises in the housing as the filter media becomes obstructed with contaminants and as the fuel additive dissolves over the life of the filter media. The top portion of the housing is made of a transparent material so that the level of fuel may be easily determined, thereby allowing for an accurate and simple assessment of the useful life of the filter media and the fuel additive. The housing also provides a multi-purpose aperture provided in the top of the housing to provide for removal and/or replacement of the fuel additive and venting and priming of the housing. The filter media and fuel additive are entirely fabricated from combustible materials so that both may be easily discarded without cost and environmental concerns.
Abstract:
A liquid filtering apparatus includes a hollow cylindrical accommodation member having external screw threads at respective ends. Connecting members are disposed at respective ones of those ends, and each connecting member possesses a passage to enable liquid to flow through the accommodation member. Each connecting member is adapted to be connected to a water pipe and is retained on the accommodation member by a respective lid member which is threaded onto a respective end of the accommodation member. A filter disposed inside of the accommodation member is in the form of a cylindrical perforated net and a panel extending across one end of the net to resist radial crushing of the net when the filter is removed and is being cleaned.
Abstract:
A readily serviceable ancillary fluid filtration system has a filter element enclosed in a container with a hose storage system. The container has a hose storage compartment for storing any unneeded length of hose. A hose management guide structure is located within the hose storage compartment to facilitate adjustment of the lengths of the hoses and storage of any unneeded length of hose after fluid filter assembly installation. The hose management guide structure includes multiple spaced-apart pegs placed within the hose storage compartment so that the hoses travel along a serpentine path within the hose storage compartment as they are fed lengthwise therein.
Abstract:
A fuel treatment apparatus and process is provided utilizing a blending head thereon defining a plurality of passages therein including a first passage and a second passage connected by a blending passage which includes a thermostat for blocking off the blending passage. The blending head functions to direct fuel into a fuel treatment apparatus having a settling chamber with a fuel introducing conduit passing through the top of the chamber and extending to a lower portion of the chamber to define a fuel inlet in the lower portion of the chamber. A buoyant valve is located within the conduit to permit fuel introduction during normal operation but to close off the conduit during periods of non-operation thus closing off fluid communication between the fuel treatment apparatus and the fuel tank. A fuel outlet is provided to remove the fuel after the treatment. A recess in the bottom of the chamber has a drain in the bottom thereof for the removal of moisture from the bottom of the chamber. A secondary fuel inlet is provided to permit introduction of fuel when the normal fuel inlet is clogged, for example, by the freezing of collected moisture therein.
Abstract:
A debris trap and in-pool skimmer for use in combination with a swimming pool cleaner having a housing; a housing lid having a conduit with an inlet and an outlet; a filter suspended within the housing; a downspout normal to and intersecting the conduit that penetrates the lid and the filter, is in fluid communication with the inlet and prevents direct flow between the inlet and the outlet; an exit port in the outlet that opens within the housing; and a one-way relief valve in the housing that opens within the filter.
Abstract:
One end of a glass tube is packed with glass powder of a predetermined size. The combination is then sintered to produce a filter within the tube. The resultant tube and filter are thoroughly washed in the direction toward the other end of the tube. The other end of the glass tube is melted to form a restriction to the flow fluid. The other end of the tube is then ground down until a microscopic orifice appears. The resultant structure is a self filtering nozzle of an exceedingly small diameter with a very low propensity to clog.
Abstract:
The invention relates to a see-through or transparent in-line filter device which is designed so that it can be inserted into a fluid line wherein there can be obtained a constant reading of the particulate contaminant in the fluid stream which passes through the filter device. There are many systems, particularly dealing with aerospace applications and processes wherein the contamination in a fluid stream must be known to the controller on a constant or periodic basis.
