Control valve for high pressure fluid
First Claim
1. A control valve for high pressure fluid comprising a valve seat, a valve, a trigger, a washer and an elastic element, said valve seat comprising a chamber, an input channel, an output channel and a pressure release channel, all of said channels being interconnected with said chamber, respectively, said elastic element, said valve and said washer being located within said chamber, said elastic element urging said valve towards said washer to block said input channel from interconnecting with said output channel, said trigger being inserted into said chamber and engaging with said valve, when a pushing force is applied to said trigger, said valve and said elastic element being pushed forward, said input channel and said output channel being interconnected and high pressure fluid being able to flow through said chamber;
- when said pushing force is disappeared, said elastic element urging said valve toward said washer, said output channel being interconnected with said pressure release channel for residue high pressure fluid to be drained out from said pressure release channel.

Abstract
A control valve for high pressure fluid includes a valve seat, a valve, a trigger, a washer and an elastic element. The valve seat comprises a chamber, an input channel, an output channel and a pressure release channel. All of the channels are interconnected to the chamber, respectively. The valve, the washer and the elastic element are located within the chamber. The elastic element is constantly urging the valve towards the trigger and against the washer to block the input channel from interconnecting with the output channel, while the output channel and the pressure release channel are interconnected with each other. When the trigger pushes the valve away from the washer, it blocks the pressure release channel and interconnects the input channel and the output channel.
