  • Patent number: 10697848
    Abstract: A logic-based building water supply management system having a minimal number of components to supply water on a qualifying-demand basis, thereby preventing major building flooding due to water plumbing leaks. The components are an electrically actuated valve downstream of the main building water supply valve, an accumulator tank immediately downstream of the valve, a tank pressure sensor, an electronic control module (ECM) and a manually operated bypass valve. The valve remains in a failsafe closed position unless a determination of qualifying demand is made. With the valve closed, all water flowing in the building may only come from the tank. As water flow stank, the measured tank supply pressure decays. The ECM compares the pressure decay rate to preprogrammed values so as to distinguish normal demand from a leak and takes appropriate action by opening the valve or disabling it from opening, and alarming, until a system reset is initiated.

  • Patent number: 8316885
    Abstract: A fluid supply system is provided, especially for delivering liquid hydrocarbon to a fuel-operated vehicle heater or to a reformer. The system includes a fluid reservoir (12), a first fluid line (28) from the fluid reservoir (12) to an on-off valve (30), a second fluid line (32) from the on-off valve (30) to a first system area (14) to be fed with fluid, and a third fluid line (34) from the on-off valve (30) to the reservoir (12). The on-off valve (30) establishes a connection between the first fluid line (28) and the second fluid line (32) in a first valve position and establishes a connection between the second fluid line (32) and the third fluid line (34) in a second valve position. A first fluid delivery arrangement (26) is provided for delivering fluid from the reservoir (12) into the second fluid line (12). A second fluid delivery arrangement (20, 24) is provided for delivering fluid from the third fluid line (34) into the reservoir (12).

  • Patent number: 8151818
    Abstract: The invention concerns a system for supplying hydraulic fluid to a hydraulic system, with an operating reservoir that accepts the hydraulic fluid provided for the operation of the hydraulic system and an auxiliary reservoir connected to the operating reservoir over a hydraulic line for intermediate storage of hydraulic fluid withdrawn from the operating reservoir. According to the invention, an air pump is available that is connected on the one hand on its low pressure side to a suction line that ends in a fluid free area of the auxiliary reservoir, so that a negative pressure can be built up in the auxiliary reservoir as against the external atmospheric pressure, and that is connected, on the other hand, to a control line that is provided with a control opening that is covered by the hydraulic fluid in the operating reservoir at least before the air pump is put into operation.

  • Publication number: 20120060950
    Abstract: A reservoir is located in a fuel tank. The reservoir is in a bottomed tubular shape having a periphery defining an opening, A lid member is located in the fuel tank and mounted to the periphery of the reservoir to close the opening. A pump unit is partially accommodated in the reservoir to discharge fuel stored in the reservoir to an exterior of the fuel tank. The pump unit is located at a position offset from a center axis of the lid member. The pump unit has a projection projected from the lid member to an exterior of the reservoir. A remaining quantity detector is configured to detect a quantity of fuel in the fuel tank. The remaining quantity detector is located at a remaining space remaining in the fuel tank. The remaining space is located on the lid member and located around the projection.

    Abstract: The invention relates to an system for supplying a hydraulic circuit with hydraulic fluid. The system includes a working reservoir and an auxiliary reservoir connected to the working reservoir by a hydraulic line. An air pump has an inlet connected to a suction line that opens into a liquid-free portion of the auxiliary reservoir so that a negative pressure can be built up in the auxiliary reservoir relative to the atmospheric ambient pressure. The air pump inlet is also connected to a control line, which comprises a control opening which is covered by the hydraulic fluid in the working reservoir, at least before the air pump is started up.

  • Publication number: 20110030822
    Abstract: Embodiments of the invention provide a pump including an inlet port, an outlet port, a pumping chamber, and a porting system. The porting system includes an inlet tube including a trap in which a first volume of fluid can be collected. The porting system includes a reservoir with a first chamber and a second chamber separated by a partial port wall. The second chamber receives fluid directed over the partial port wall from the pumping chamber. The reservoir collects a second volume of fluid substantially equal to the first volume of fluid. The first volume of fluid and second volume of fluid provide enough fluid trapped inside the pump to allow the pump to temporarily operate when substantially no fluid is flowing into the inlet port.

  • Patent number: 7641453
    Abstract: A pulsation reducing apparatus is used for an apparatus having a pump for circulating a liquid in a circulating line and a tank for storing the liquid circulating via the pump. The pulsation reducing apparatus includes a supplement tank for reserving the liquid such that a liquid surface height of the supplement tank is higher than that of the tank. The tank is connected to the supplement tank and the empty space portion of the tank is connected to the supplement tank via a gas exhaust line. When the empty space portion of the tank communicates with that of the supplement tank via the gas exhaust line due to a reduction of the liquid in the tank, the gas in the tank is exhausted to the empty space portion of the supplement tank via the gas exhaust line and the liquid in the supplement tank is supplemented into the tank.

  • Patent number: 7389768
    Abstract: A pump module, which is mounted to a fuel tank, includes a sub-tank, a fuel pump and an elastic member. The sub-tank is accommodated in the fuel tank. The fuel pump is accommodated in the sub-tank to pump fuel drawn into the sub-tank. The elastic member is formed of an elastomer, and is interposed between a bottom portion of the sub-tank and a bottom portion of the fuel tank. The elastic member makes contact with fuel. The elastic member internally has spaces to release stress that arises in the elastic member due to swelling caused by contacting with fuel. The elastic member is formed in a sheet. The elastic member is mounted to the sub-tank via an outer periphery of the elastic member. The spaces are arranged in a substantially circumferential direction of the sub-tank, or are arranged in a substantially radial direction of the sub-tank.

  • Publication number: 20080011354
    Abstract: A new and useful system and method is provided, designed to conserve existing water resources, and also to provide additional benefits to a water supply, particularly to a water heater. In a system and method of the invention, a source of water condensate is in fluid communication with a reservoir. A primary water flow path is established between water from a primary source and a water heater, and a hydrostatic connection is provided between the reservoir and the primary flow path. The hydrostatic connection is designed such that water from the reservoir is drawn into the primary flow path and mixed with the water in the primary flow path, thereby enabling the water condensate from the reservoir to supplement the flow of water in the primary flow path to the water heater.
