ABSTRACT:
An inlet valve assembly for an air compressor and/or compressor-exhauster having a plug member disposed in a cylinder head. A buffer plate screwed onto the lower end of a multi-threaded stud. A spring plate disposed on top of the buffer plate and a guide ring located between the spring plate and a valve plate. An inlet valve seat disposed above the valve plate and a lockout screwed onto an intermediate threaded portion of the multi-threaded stud. An inlet valve unloader slidably mounted on guide bushing and a lockout screwed onto the upper end of the multi-threaded stud. An unloader return spring caged between the inlet valve spring and the inlet valve unloader. A plurality of radially extending tab portions led along the peripheral edge of the buffer plate for preventing parts of the inlet valve from falling into the compressor chamber when the multi-threaded stud breaks.
