摘要： A hydraulic system having a standpipe in a sump with ports on the side of the standpipe and one smaller port on the top of the standpipe. The majority of the oil flows into the standpipe through the side ports thereby reducing the downward suction and flow at the top of the standpipe to eliminate the formation of a vortex at the top of the standpipe. As a result, less air is drawn into the oil producing a more consistent oil/air mixture and more consistent sump oil level.

摘要： A sewage system comprising a network of sewage sumps that temporarily store sewage produced in a dwelling or other structure, each of said sumps preferably comprising a computer controller for operating a pump in the sump such that the sewage collected in the sump may be pumped out of the sump and into the collection system in a controlled manner to regulate the flow of sewage material in the system. The regulation of the sewage flow permits the efficient operation of a sewage treatment facility that receives sewage from the network of sewage sumps by insulating the facility from the peak burdens that would be placed on it at certain times of day in the absence of a system that regulates sewage flow into the system at the source of the sewage.

摘要： A reservoir for power steering fluid includes an upright housing that forms an upper interior space for storage of a reserve fluid supply, and a lower interior space containing a fluid filter. Fluid connectors are provided for causing fluid to flow in a circumferential swirling pattern as it moves through the filter, such that the flowing fluid has a relatively long residence time in the lower portion of the reservoir for achievement of an effective cooling action. The fluid filter is connected in a return line form the power steering unit to the associated pump, so that the filter exerts a back pressure on fluid flowing from the power steering unit to the filter.

摘要： A liquid dispenser and control system includes a base member having an intake cavity with an axis for orientation in an upward direction, the intake cavity being sealingly mateable with a mouth opening of a replaceable liquid container which, when mated with the intake cavity, is in an inverted position for draining liquid through the mouth opening into the intake cavity. The intake cavity includes a sump into which liquid from the container can drain by gravity. The vent tube assembly has an intake end connectable to atmosphere or a source of gas, the vent tube assembly extending from the base member through the intake cavity, and has a venting end for positioning inside the container. A passageway extends through a portion of the base member, the passageway having an entry end and an exit end, the entry end connected to the sump, through which liquid from the sump can drain into the passageway. A sensor has a fluid path therethrough connected to the exit end of the passageway, the sensor for detecting when liquid flow through the passageway from the container ceases and is followed by gas from the container entering the sensor. A liquid conduit is connected to the fluid path of the sensor, for receiving liquid passing through the sensor.

摘要： A plurality of drainage pumps are disposed on a high floor gradation state in a circular arrangement. A plurality of drainage pumps are disposed on a low floor gradation state in a circular arrangement. The drainage pumps disposed on the high floor gradation are installed at a high level, with the drainage pumps having a low pump head and a large capacity in comparison with the drainage pumps disposed at the low floor gradation. An outer shape of an underground pump construction building is in the form of a circular cone shape spreading toward an upper portion of the underground pump construction building. The amount of power for discharging the drainage can be reduced and the construction area for the underground pump construction building can be reduced thereby minimizing the necessary requirement for installation of the underground pump construction.

摘要： A device for a dishwasher comprising a tub with a bottom (10) which is provided with a sump (11) for collecting liquid circulating in the tub. When the machine is emptied, the liquid is distributed from the sump to the inlet side of a sewage pump (20) from which the liquid is discharged to a sewer or the like. In order to make the overall height of the machine small, to limit the quantity of watr remaining in the sump, and to considerably decrease the working time of the sewage pump necessary to achieve this small quantity, the bottom surface of the sump (11) is placed below or on the same level as the pump housing (23), and the inlet (21) of the pump communicates with the sump via a pipe (17) which has a restriction (26).

摘要： A scavenger system (10) for a hydraulic recirculating installation, such as may be employed with a vehicular transmission (11), which employs a sump (18) to collect the recirculating hydraulic fluid (19). The sump (18) is to be maintained essentially dry, and as a result the requisite volume of hydraulic fluid (19) for the recirculating installation is stored within an independent reservoir (28). The sump (18) is provided with one or more collecitng wells (21), and a unique pickup head assembly (22) is received within each well (21). The pickup head assembly incorporates capillary ducts (46) which control communication between the well (21) and the conduit means (29) in response to the hydraulic fluid (19) within the well. The capillary filter serves to admit the flow of hydraulic fluid freely therethrough but precludes the passage of air therethrough. A circulating pump (25) has an inlet port (30) which communicates with the reservoir (28) by virtue of a conduit means (29). The conduit means (29) also effects communication between the inlet port (30) of the pump (25) and each pickup head assembly (22).

摘要： A circular plate extends across the diameter of "sump suction" pump, with a close clearance between the edge of the plate and the wall of the pump tank. The plate is located above the pump impeller, inlet and outlet flow nozzles but below the sodium free surface and effectively divides the pump tank into two separate chambers. On change of pump speed, the close fitting flow restriction plate limits the rate of flow into or out of the upper chamber, thereby minimizing the rate of level change in the tank and permitting time for the pump cover gas pressure to be varied to maintain an essentially constant level.
