  • Publication number: 20110135505
    Abstract: A pump device for feeding fuel in a fuel tank of a motor vehicle, having a suction jet pump and having a control valve for regulating the feed rate of the suction jet pump, A valve body can be moved counter to the flow direction of a fuel jet of the suction jet pump to throttle the feed rate. In this way, forces for opening the control valve are kept low. A float controls the valve body via a shaft which is guided through a mixing tube of the suction jet pump.

  • Patent number: 6736603
    Abstract: An oil suction pump includes a push switch, a shaft vertically located below the push switch, and a float arm horizontally located below the shaft. A hooked lower end of the shaft is adapted to detachably engage with a hooked first end of the float arm and thereby holds the shaft in a fixed position when the push switch is depressed. A second end of the float arm is pivotally connected to a float that ascends when the oil sucked into a container connected to the oil suction pump reaches a predetermined level and thereby causes the first end to descend and disengage from the hooked lower end of the shaft, allowing the latter to move upward into an original position and automatically close an air inlet valve of the oil suction pump.

  • Patent number: 6537036
    Abstract: A flow amplifying pump apparatus includes a body member that defines a flow passageway and a compressed air inlet. The body member includes a main segment and an insert segment which extends into a container and rotates relative to the main segment. A cover member which lies releasably secured to the body member supports a plug assembly. The plug assembly includes a plunger that defines a groove for cooperating with a protuberance in the cover member to guide the plunger along a predetermined, substantially linear path.

  • Patent number: 6527518
    Abstract: A water-powered sump pump that utilizes a relatively higher pressure water ported through a self-reversing valve to a reversible stroke power cylinder having a movable member mechanically coupled to a pumping chamber for movement of a movable pumping member in the pumping chamber, movement of the movable pumping member forcing sump water to a discharge. The volumes of the power cylinder and pumping chamber are different such that relatively high pressure, low volume flow to the power cylinder results in relatively high volume, low pressure flow from the sump pumping chamber. The discharge from the power cylinder is backflow prevented with respect to the discharge from the sump pumping chamber.

  • Patent number: 6224345
    Abstract: A pressure/vacuum generator is established by coupling the pressure port of a vacuum generator to an air pressure source while coupling a valve in fluid communication with the exhaust port of the vacuum generator. When the valve is in a normally open condition (i.e, the exhaust vented to atmosphere), the vacuum port of the pressure/vacuum generator generates a vacuum. When the valve is closed, thereby closing off the exhaust port, the vacuum port becomes a pressure port. Thus, this pressure/vacuum generator can be used in any number of fluid (liquid and gas) systems (e.g., fluid recovery system, fluid transfer system, etc.)that require both a pressure source and a vacuum source while using a minimum number of components.
