WIPO Patent Application WO/2018/088818
Kind Code:
A1
Abstract:
The present disclosure relates to a hydraulic/pneumatic check valve which can prevent a fluid or gas from coming into direct contact with a spring, so as to prevent flow resistance and turbulence from being formed and thus allow the fluid to move smoothly, and can prevent the occurrence of noise, which may be generated by direct contact between the fluid or gas and the spring. In order to achieve this aim, the hydraulic/pneumatic check valve may comprise features such as: a body; a first and second coupler; a check poppet comprising a poppet head and a poppet guide; a guide ring; an adjuster; and an elastic member.
