Abstract
A pressure reducing valve assembly ( ) for receiving fluid from a high pressure line and delivering the fluid to a low pressure line includes an elongated tubular body ( ), a pressure reducing valve (14) having a single, valved opening ( ) interposed between high and low pressure ports ( ),( ), and a pressure reducing reservoir ( ) defined substantially between the body ( ) and the pressure reducing valve ( ). The pressure reducing reservoir ( ) comprises the only substantial fluid communication between the body ( ) and the pressure reducing valve ( ) and fluidly communicates with the high pressure port ( ) by the single, valved opening ( ). In preferred forms, the pressure reducing valve ( ) includes a valve insert ( ) housing a spring ( ) 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 ( ).
