Abstract
A pressure reducing valve assembly (10) for receiving fluid from a high pressure line and delivering the fluid to a low pressure line includes an elongated tubular body (12), a pressure reducing valve (14) having a single, valved opening (54) interposed between high and low pressure ports (68),(70), and a pressure reducing reservoir (16) defined substantially between the body (12) and the pressure reducing valve (14). The pressure reducing reservoir (16) comprises the only substantial fluid communication between the body (12) and the pressure reducing valve (14) and fluidly communicates with the high pressure port (68) by the single, valved opening (54). In preferred forms, the pressure reducing valve (14) includes a valve insert (64) housing a spring (62) that, among other functions, serves as a reset valve to further reduce the space requirements and decreasing the cost and complexity of the valve assembly (10).
