    摘要： A check valve is provided for use with variable frequency drives and other applications. In one aspect, the check valve provides a poppet guided by a poppet guide in at least two locations to ensure stability between fully open and fully closed positions. In another aspect, the check valve includes a poppet guide adapted to receive a poppet in a stem receiving channel, the stem receiving channel including guide vanes engaging the poppet and auxiliary channels for self cleaning. The check valve may also include a valve seal. In one embodiment, the valve seal is an o-ring received by a poppet head, based of the poppet guide and valve seat. The valve seat and/or the base may include expansion channels to receive a portion of the valve seat during compression when the check valve is in a closed position.

    摘要： A pressure relief valve for pressure equalization between an essentially closed space and the surrounding atmosphere is disclosed. The pressure relief valve includes a valve housing with: a cylindrical wall defining a flow passage, a valve body arranged to cooperate with a valve seat arranged in the outflow of the valve housing, a stem configured for axial guidance of the valve body, a lifting element or plate arranged further down in the flow passage relative to the valve seat, a flow constriction defining an essentially truncated conically shaped interior and arranged to encircle the lifting element such that a radial passage between the lifting element and flow constriction increase when the lifting element and the valve body is moved from a closed state of the pressure relief valve towards an open state of the pressure relief valve.

    摘要： A degassing valve in a flexible container is disclosed. The valve includes a generally flat valve seat on a truncated generally dome shaped structure, and the valve seat is raised a height above the valve chamber base surface. A resilient, non-perforated, non-spring-biased diaphragm is inter-engaged upon the valve seat and overlaps the valve seat outer periphery. The valve seat engages a central area of the diaphragm that is not proximate the perimeter of the diaphragm, and the dome shaped structure has a sectional radius greater than the diaphragm radius. A well is recessed into the valve seat in a direction away from the diaphragm by a depth less than the height of the valve seat above the valve chamber base surface.

    摘要： A transmission has a housing with interior and an exterior surfaces. A fluid passage is located in the interior of the housing. A ball-check assembly has a ball; a conical retaining chamber with an end with an inner diameter greater than the diameter of the ball, and an end with an inner diameter less than the diameter of the ball; and a conical wall extending between the two ends. The fluid passage is in fluid communication with the ball check assembly. The ball is located in the conical retaining chamber and is dimensioned to become wedged against the conical wall as the ball is moved from the greater diameter end toward the lesser diameter end, thereby providing a seal between the ends of the conical retaining chamber.
