摘要： A valve assembly for fluid pressure regulation provides freedom from static pressure creep by eliminating distortions and stresses normally introduced to valve parts during assembly of the regulator. A floating valve seat permits normal installation of a valve seat housing in the regulator body with no transfer of stress or distortion to the valve seat. Thus statis pressure creep, normally attributable to micro distortions of the valve seat, is avoided. Options are also provided to install the floating valve seat directly in a regulator body without the valve seat housing.
摘要翻译：用于流体压力调节的阀组件通过消除在调节器组装期间通常引入阀部件的变形和应力而提供无静压蠕变。浮动阀座允许在调节器主体中正常安装阀座壳体，而不会向阀座传递应力或变形。因此，避免了通常归因于阀座的微小变形的状态压力蠕变。还提供了将浮动阀座直接安装在没有阀座壳体的调节器主体中的选项。

The reciprocating pump includes a reciprocating pump having a pump chamber with a rod reciprocally movable along a longitudinal axis of the pump chamber, with the rod including a ferromagnetic material. An induction coil disposed around the rod wherein relative axial movement between the inductance coil and the ferromagnetic material of the rod varies the inductance of the induction coil. Also provided is a reciprocating pump having an active feedback system in which the rod has an electrically conductive, diametrically tapered portion. A linear displacement sensor is disposed next to the tapered portion which induces a current in the tapered portion and generates an output voltage proportional to a relative position between the linear displacement sensor and the tapered portion.
