Abstract:
A fluid valve for controlling the flow of fluids comprising:an outer housing having a flowbore for the flow of fluids;a piston member reciprocably and rotationally retained within the flowbore of the housing for movement therewithin in response to fluid flow or non-fluid flow through the flowbore;a translational member retained within the housing for axial movement with the piston member; andthe piston member and translational member each having at least one fluid port in fluid communication with the flowbore, the at least one fluid ports opening upon reciprocal and rotational movement of the piston member within the housing in one direction during fluid flow through the flowbore and closing upon reciprocal and rotational movement of the piston member in another direction upon non-fluid flow through the flowbore.
