    • A gas pressure regulator includes a body having respective inlet and outlet ports and an interior chamber defining a gas flow path. A hollow piston is moved in relation to a valve seat to create a junction through which gas is directed along the flow path to the outlet port. The piston engages a valve seat, thereby defining relative open and closed positions based on the position of the piston and the pressure of the gas, the piston being axially biased by a spring. The valve seat is attached to an adjustment member having at least one externally accessible feature to enable the axial position of the valve seat to be varied relative to the spring biased piston. In one version, the gas pressure regulator can include a heater assembly extending into the flow path adjacent the outlet port, enabling ported gas to be heated before introduction, e.g., into an engine.

    • A water pressure reducer using compression forces with an inverse upstream to downstream pressure relationship, and a method of operating the same, is disclosed. The water pressure reducer may include a housing defining first and second chambers separated by a membrane. Water pressure within the second chamber biases the membrane in a first direction opposite the force of a spring within the first chamber, decreasing flow through a valve seat and into downstream water lines. Decreased water pressure within the second chamber biases the membrane in a second direction, increasing flow through the valve seat and water flow to downstream pipes. Biasing of the membrane in the first direction and the second direction can occur continuously as water pressure from the upstream water line increases and decreases.
    • 公开了一种使用反向上游到下游压力关系的压缩力的水减压器及其操作方法。 水减压器可以包括限定由膜隔开的第一和第二室的壳体。 第二腔室内的水压力使第一方向上的膜与第一腔室内的弹簧的力相反,减小了流过阀座的流量并进入下游的水管线。 第二室内的水压降低使膜在第二方向偏压,增加通过阀座的流量,并向下游管道提供水流。 随着来自上游水线的水压力的增加和减少,膜在第一方向和第二方向上的偏压可以连续地发生。
