Reciprocating compressor providing a lubricant free compressed gas
This patent describes a reciprocating compressor. It comprises: a housing including means defining at least one cylinder; a piston reciprocally received in said cylinder; a drive shaft journaled in said housing; a piston rod connected to said piston and extending toward said drive shaft; a rotary to reciprocating motion converting mechanism interconnecting said piston rod and said drive shaft so that rotation of said drive shaft will cause reciprocation of said piston; means for providing liquid lubricant to said converting mechanism to lubricate the same; means for positively isolating said cylinder from said liquid lubricant for all positions of said piston within said cylinder including a bellows having opposed ends and surrounding said piston rod between said piston and said converting mechanism; and an imperforate cup-like web carried by said rod and having a peripheral lip displaced away from one of said cylinder and said converting mechanism.
