    摘要： A fuel pump module includes a reservoir configured to hold a supply of fuel. The reservoir includes a fuel passageway and defines a first seat on a first side of the fuel passageway and a second seat on a second side of the fuel passageway. The module also includes a seal configured to be seated on the first and second seats to substantially seal the fuel passageway, and a weight biasing the seal toward the first and second seats by contacting the seal only at a location between the first and second seats. A gap may be defined between the weight and the seal, allowing fuel to enter the gap and further bias the seal toward the seats.

    摘要： The present invention discloses a fluid relief device for relieving pressure of a fluid stored in a container or tank, or fluid used in a piece of equipment. In one aspect such a device has a body member with a primary channel therethrough in communication with a container of a contained fluid under pressure. When the pressure of the contained fluid under pressure exceeds a predetermined level, the pressure of the contained fluid moves a cover which is sealingly in place to close off the primary channel. During normal conditions the force of the contained fluid is insufficient to move the cover and leakage of the contained fluid past the cover is inhibited by the provision of a barrier fluid supplied into a barrier fluid chamber to oppose the contained fluid, the barrier fluid at a pressure greater than the normal pressure of the contained fluid. Seals may be provided on one or two sides of the barrier fluid chamber--a first seal to seal the primary channel-chamber interface and a second seal to seal the chamber-exterior interface. Fluid under pressure supplied to the chamber may leak past the first seal into the container. In one aspect an inert barrier fluid, e.g. nitrogen is used. Devices according to this invention may be used with pressure relief devices and vacuum relief devices.

    摘要： A pressure regulating valve 10 is provided in a housing 11 filled with oil 23 and having an inlet port 12 and an outlet port 13. A straight elongate vertical tube 14 having a lengthwise slot 19 near its lower end 15 is affixed to the housing and communicates with the inlet port. Closely fitting down into the tube is a piston 16, slidable between a lower position 29 with its lower end 17 below the slot and a substantially higher upper position. A coaxial annular weight 22, surrounding upper portions of the piston and the tube, is affixed to the piston to exert a downward force thereon by virtue of the gravitational attraction of the weight to the earth. When oil is supplied under pressure to the inlet port, the oil presses upward, and the weight presses downward, against the piston; and when the lower end of the piston is at a level between the ends of the slot, the oil flows in from the inlet port, through the open portion of the slot, into the other space in the housing, and out through the outlet port, at a substantially constant predetermined pressure.
