Abstract
A pressure reducing valve assembly (10) includes an elongated tubular body (12), a pressure reducing valve (16) for reducing the fluid pressure discharged from the valve assembly, a pressure relief valve (18) for permitting fluid to discharge from the valve assembly when the device to which the valve assembly is coupled experiences an over-pressure condition, and a reset valve (20) for resetting the pressure reducing valve when the fluid pressure on the high pressure side of the valve assembly is reduced below a pre-selected reset level. The pressure reducing valve, pressure relief valve, and reset valve are all positioned within the tubular body and coaxially aligned along the longitudinal axis (14) of the body. The reset valve is positioned within the confines of the pressure reducing valve, and the pressure relief valve utilizes the same compression spring (90) as the pressure reducing valve.
