Abstract

See full text

An inline valve includes a sliding piston having a radially outer stop portion with a forward end. A radially inner sliding portion is connected to the radially outer stop portion by an arm. A housing includes an outer housing body surrounding the piston. The housing has a stop surface selectively in contact with the forward end of the radially outer stop portion of the piston to block flow for a housing inlet to a housing outlet. The radially inner sliding portion slides on a support tube. At least a portion of the radially inner sliding portion is formed of a first material having better wear resistance than a second material forming the outer stop portion of the piston. The second material has a greater resistance to high temperature and pressure than the first material. A vent valve for a compressor is also disclosed.
