ABSTRACT:
An improved fluid regulator is provided for receiving high pressure fluid and controllably outputting low pressure fluid. The regulator valve mechanism includes a regulator seat fixed to the regulator body and a regulator valve disk movable within the regulator body for sealing engagement with the seat. A spring-biased piston is provided axially movable within a piston housing in response to the low pressure fluid, and has a port therethrough. A relieving valve mechanism includes a seat formed on the regulator valve disk, and a dart member carried by the piston and having a flow passageway therethrough in fluid communication with the port in the piston. The regulator of the present invention is self relieving to ensure that pressurized fluid will continually be supplied to downstream equipment. The sensitivity of the regulator is enhanced, and the regulator is designed for low cost maintenance.
