摘要： An intake chamber (10) for an operating medium pump for sucking up operating medium stored in an operating medium tank of a motor vehicle, comprising a housing (20) in which at least two inlet openings (31, 32) for admitting operating medium to a connection (60) formed in the top side of the housing (20) are formed, wherein a deflecting wall (51, 52) is arranged in the housing (20) be-tween each inlet opening (31, 32) and the connection (60). Undercuts (81, 82) are formed on the inside of the inlet openings (31, 32). A suction jet pump or operating medium pump with at least one such intake chamber 10 is also disclosed.

摘要： A water-powered sump pump including a chamber with a water supply inlet, wastewater inlet and a discharge outlet, wherein a venturi is secured within the chamber, and an elbow joint, including a wastewater exit portion and a wastewater entrance portions. This elbow joint is rotationally securable to the wastewater inlet of the chamber to permit securing of the water-powered sump pump in any desired orientation in relation to the sump. In one embodiment the wastewater inlet includes a cylindrical ingress portion with an upwardly facing ridge around a circumference thereof. The securing system of the elbow joint includes tabs on an inner surface of the exit portion of the elbow, each tab containing an inwardly extending rib which rib extends beyond the upwardly facing ridge on the ingress portion of the wastewater inlet when the elbow joint is secured onto the wastewater inlet.

摘要： A fuel system includes a fuel reservoir configured to be located within the fuel tank such that the fuel reservoir defines a fuel reservoir volume which is a subset of a fuel tank volume; a fuel pump configured to pump fuel from within the fuel reservoir volume to the fuel consuming device through a fuel supply line; a jet pump configured to 1) receive excess fuel, through a fuel return line, which had been supplied to the fuel consuming device through the fuel supply line and 2) aspirate fuel into the fuel reservoir volume from the fuel tank volume; and a valve which allows fuel flow in both directions between the fuel return line and the jet pump when a differential pressure across the valve is greater than or equal to a predetermined threshold.

摘要： The technology relates to a submersible water lifting assembly and automatic fire fighting system for unmanned platforms having said system (1) that is efficient yet simple to install, energy saving, noise free and economical. The submersible water lifting assembly can comprise a High flow Ratio ejector Pump (30/30A) that utilizes under water arrangements of unmanned platform and enables the fire-fighting system to efficiently lift water from the sea water; using the force of existing water injection system; eliminating the requirement of diesel engine driven pump, for lifting the water. It avoids fire risk of the safety system itself, even in conditions of a large fire, unlike that of the prior art.

摘要： A liquid suction pump comprising: a drive pipe to receive a liquid drive flow for the pump; a liquid conduit with first and second liquid delivery arms to provide pumped liquid, and a connecting valve arrangement between the arms. First and second pump inlets to the arms have respective first and second one-way inlet valves. The valve arrangement has a valve inlet coupled to the drive pipe and valve outlets coupled to the arms to alternately close off a liquid connection between the valve inlet and respective arms. A compliant element is coupled to the drive pipe. The drive flow oscillates in pressure/flow rate due to alternate switching of the valves. A compliance of the compliant element is such that a geometry of the suction pump in combination with the compliance defines a resonant condition, and the oscillation is at a resonant frequency of the pump.

摘要： Methods for drafting or transferring water from a water supply to a fire pump in fire service include a strainer, the strainer having a hood member with an open bottom inlet having an inlet aperture, an outlet having an outlet aperture, a suctioning structure extending away from the open bottom inlet of the hood member, and the suctioning structure having a base offset from the open bottom inlet. Method of using the strainer including immersing a strainer in a water supply, fluidly connecting the outlet to a suction side of a pumping apparatus, activating the pumping apparatus, transferring water through the hood member, directing the strainer toward the bottom of the water supply and maintaining the strainer at the bottom of the water supply.

摘要： A hydraulic circuit includes a pump in fluid communication with a reservoir containing a liquid to be pumped. The pump includes an inlet and an outlet. The hydraulic circuit also includes a venturi pump in fluid communication with the reservoir and with the outlet of the pump, and an injection valve including a cooling feature. The injection valve is in fluid communication with the outlet of the pump, and is configured to dispense liquid supplied to the injection valve by the pump. The cooling feature is in fluid communication with the venturi pump. The pump is configured to produce a first flow of liquid, and the hydraulic circuit is configured to supply a first portion of the first flow of liquid to the injection valve for dispensing by the injection valve and a second portion of the first flow of liquid to the venturi pump.
