Abstract

The present invention describes a safety mechanism for a directional control valve. The mechanism may be implemented in various valve configurations commonly found in the directional control valve industry, including but not limited to those suitable for incorporating a pneumatic fluid reuse delay function. The present invention relates generally to the field of directional control valves, and more particularly to the field of pneumatic directional control valves with a fluid recirculation delay function.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 783,164, filed March 14, 2013, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to the field of directional control valves, and more particularly to the field of pneumatic directional control valves with a fluid recirculation delay function. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Directional control valves are well established in modern industry for regulating and controlling the flow of fluids through systems. Directional control valves designed for pneumatic applications, often referred to as "pneumatic valves," are used to regulate the flow of gaseous fluids. Often, these pneumatic valves are used to provide a means of transferring mechanical ...
