发明名称 Valve i.e. pressure relief valve, for deep mining, has piston guide comprising conducting surface erecting impact surface of piston, such that fluid leaking-out of piston guide subjects piston with dynamic fluid pressure in axial direction
摘要 <p>The valve has a valve body formed from housing halves (10, 12). A valve piston (20) is subjected by a spring (18) and is inserted into a piston guide (16). The piston guide comprises a conducting surface, which bypasses fluid leaking-out via an opening valve of the piston guide in an axial direction. The conducting surface erects a radially oriented impact surface of the valve piston, such that the fluid subjects the valve piston with dynamic fluid pressure in the axial direction. The valve piston is formed as circle-cylindrical tap within a region of the piston guide.</p>
