摘要： A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The by-pass flow path may be sealed off when a compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.

摘要： A fuel filter system that does not require the periodic draining of a water sump. The system includes a fuel tank for storing fuel and a fuel filter fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side and a high pressure side. The high pressure side of the fuel pump is fluidly coupled to the fuel filter for pumping fuel to the fuel filter. A water emulsifier, such as an orifice, is fluidly coupled to the fuel filter to receive water and fuel from the fuel filter and form a water-fuel emulsion. The water-fuel emulsion is supplied to any point in the system on the suction side of the fuel pump, such that the water-fuel emulsion passes through the fuel pump and fuel filter.

摘要： A filter insert for a filter for filtering a fluid having] an inflow surface, and outflow surface, and a main throughflow direction. A filter body of the insert has a filter medium with pleats forming a pleated bellows, are arranged perpendicular to the main throughflow direction. A first number of the pleat edges form the outflow surface and a second number of the pleat edges on a pre-filtration side of the filtration body form the outflow surface. A first seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration on a surface formed by a first number of of end face of the pleats. A second seal prevents the fluid from overflowing from the pre-filtration side to the post-filtration side on a surface formed by a second number of end faces of the pleats.

摘要： The liquid recovery filter includes several embodiments, each of which provides for the recovery of liquid otherwise trapped within the filter housing and element. Each embodiment includes a series of vents, purge ports, and passages that communicate fluidly with the filter housing and filter core. Certain vents and purge ports are initially opened following filtration operations to allow pressurized gas to flow into the housing, thereby forcing residual unfiltered liquid through the filter. When this has been accomplished, another vent is opened to the filter core to allow filtered liquid to flow from the downstream or outlet passage from the filter core. Some embodiments have the filter outlet located above the filter, and include a downstream drain port extending from the filter core. The downstream drain port provides for the recovery of filtered liquid when the vent or purge port is opened in these embodiments.

摘要： The filter element includes a filter medium having an axis and forming a channel extending substantially axially, a first and a second end plates, each end plate covering one axial end of the filter medium and being sealingly mounted on the axial end, the first end plate having an opening in fluid communication with the channel, whereby a liquid to be filtered can flow through the filter medium towards the channel and out of the filter element through the opening, or reversely. The filter element further includes a protrusion fixedly secured to the first end plate and extending outwardly from the first end plate, the protrusion being substantially tubular and having a through hole in fluid communication with the first end plate opening, the protrusion forming a female coupling piece of a male-female connector, and a locking member capable of releasably locking a male coupling piece of the male-female connector in the female coupling piece.

摘要： A filter device comprises a hollow cylindrical filter element in a filter housing. The fluid that is to be purified is to radially flow through the filter element. The interior of the filter element forms an axial flow chamber for the fluid. An end plate is arranged on the front side of the filter element. An annular neck, onto which a sealing element is injection-molded, is connected to the end plate.

摘要： A filter element has a preferably multilayer structure of a pleated filter medium (3) with a plurality of individual filter pleats (5, 7). Due to an alternating sequence of filter pleats (5) with a first pleat height (h1) and filter pleats (7) with a second pleat height (h2), more effective filter surfaces are available than with filter pleats with a uniform pleat height. Upon throughflow by a fluid to be filtered, a lower surface load for the filter medium (30 and lower passage speed of the fluid are present during filtration. A static loading of the filter medium (3) during operation of the filter is then reduced. A hydraulic circuit has such a filter element (1).

摘要： A work vehicle includes a work implement and an operating fluid tank. The operating fluid tank has a tank body and a strainer. The tank body is for collecting operating fluid for driving the work implement. The strainer is installed inside the tank body and includes a cylindrical filter and a cover member. The cylindrical filter is disposed with an axis extending in a vertical direction. The cover member includes an upper plate part and a cylindrical part. The upper plate part of the cover member covers an upper surface of the filter. The cylindrical part of the cover member extends downward from an outer edge part of the upper plate part and covers an upper side surface part of the filter with a gap between the side surface of the filter and the cylindrical part, while allowing a lower side surface part of the filter to be exposed.

摘要： A filter material for a filter insert of a fuel filter for separating solid particles and water droplets from fuel. The filter material comprises a particle filter medium layer through which the fuel flows first during use and at least one coalescer medium layer which lies on the particle filter medium layer on the outflow side. At least one coalescer medium layer is gradient-free in the flow direction with respect to the geometrical structure and/or physical properties and/or chemical properties of the layers. The at least one coalescer medium layer has a thickness measured in the flow direction which is maximally as large as the thickness of the particle filter medium layer measured in the flow direction.
