摘要： A metering valve for metering dry powder material such as cement. The interior of the valve housing is expanded outward beginning at the sealing surface or lip located adjacent to the inlet opening, thereby forming an enlarged gap between the valve sleeve and housing to discourage powder accumulation in the gap and interference of large bulk particles and foreign materials with the sleeve and housing. An eccentric intermediate sleeve aligns the valve sleeve relative to the housing prior to rotation of the valve sleeve by either moving the valve sleeve away from or toward the valve inlet. The valve sleeve has a rubberized layer to seal with the housing's sealing surface or lip. A sleeve shield blocks entry of powder into the mouths of the vacuum breakers to prevent plugging of the vacuum breakers. Ball bearings are employed to suspend the valve sleeve within the housing, making the valve sleeve easier to rotate.

摘要： A fuel cutoff valve of the invention has a casing main body, a first float having a smaller specific gravity than that of a fuel, a second float having a greater specific gravity than that of the fuel, and a spring. The first float has a float main body and a buoyancy body of a foamed resin. The buoyancy body makes the resulting specific gravity of the first float smaller than the specific gravity of the fuel. The first float moves up by means of buoyancy to close a first connection conduit, when a liquid level in a fuel tank exceeds a first present liquid level. The second float moves up by means of buoyancy and a pressing force of the spring to close a second connection conduit, when the liquid level in the fuel tank exceeds a preset second liquid level, which is higher than the preset first liquid level. The second float moves down to open the second connection conduit, when the liquid level becomes lower than the preset second liquid level but is still higher than the preset first liquid level. This structure of the fuel cutoff valve effectively prevents leakage of the fuel from the fuel tank even under a large transverse force, for example, at the time of a turn of a vehicle, or under a large upthrust force.
摘要翻译：本发明的燃料切断阀具有壳体主体，具有比燃料小的比重的第一浮子，比重大于燃料的第二浮子以及弹簧。第一浮子具有浮子主体和发泡树脂的浮力体。浮力体使得所得到的第一浮子的比重小于燃料的比重。当燃料箱中的液面超过第一现有液位时，第一浮子通过浮力向上移动以关闭第一连接导管。当燃料箱中的液位超过预先设定的第二液位时，第二浮子通过浮力和弹簧的按压力向上移动以关闭第二连接导管。当液位低于预设的第二液位但仍高于预设的第一液位时，第二浮子向下移动以打开第二连接导管。燃料切断阀的这种结构即使在大的横向力的情况下，例如在车辆转弯时，或者在大的上推力下，也能够有效地防止燃料从燃料箱泄漏。

摘要： An in-line vacuum breaker for a flexible hand held shower. The vacuum breaker includes a frusto-conical body with a water flow passage extending therethrough. The frusto-conical body has an inlet cavity at one end and an outlet cavity at the opposite end. An outlet plug is threaded into the outlet cavity. A first passage formed in the outlet plug leads to an outlet opening. A second passage in the outlet plug extends parallel to the first passage and leads to a vent opening. A manifold passage defined in the outlet cavity by the body and the outlet plug connects the body passage and the first and second passages. A first check valve in the first passage permits fluid flow only from the manifold passage to the outlet opening. A second check valve positioned in the second passage prevents fluid flow from the manifold passage to the vent opening. A third check valve positioned in the body passage permits fluid flow only from the body inlet opening to the manifold passage.

摘要： A vacuum breaker having a floating piston that is movable in response to the communication of negative pressure to an inlet port of the vacuum breaker for permitting venting of fluid to the outside atmosphere through a vent opening. The vacuum breaker includes a liquid capture and containment device, which in conjunction with an outer hood, is effective for capturing and containing liquid in a fluid flow stream discharging from the vent opening and redirecting the captured liquid back into the vacuum breaker in order to prevent water leakage.

摘要： In a method of pressure and/or gas volume compensation within a fuel tank in relation to movement-induced and/or temperature-induced changes in pressure and/or volume, as when fuel is drawn from the tank and upon refuelling of the tank, any changes in pressure outside a predetermined normal pressure range are compensated by condensation of the gaseous fuel or gasification of the liquid fuel within a system which is hermetically closed off at least above atmospheric pressure. The invention also provides a tank operating on that basis.

摘要： A float operated fuel vapor vent valve for use in a vehicle fuel tank. The float has a membrane valve caged for lost motion movement on the top of the float. Upon refueling, the float rises and seals the membrane on a vent port valve seat. A projection extending downwardly from the top of the cage contacts the membrane to peel away a localized area of the membrane valve from the valve seat to ensure re-opening upon the float descending as fuel is withdrawn from the tank.
