Abstract:
A single-headed piston type compressor comprising:a housing including a suction chamber, a discharge chamber and a crank chamber therein; a drive shaft rotatably supported by said housing, wherein a first end of said drive shaft protrudes from said housing, and a second end of said drive shaft is disposed within said housing, and the suction chamber of said housing is defined adjacent to the first end of said drive shaft such that said drive shaft penetrates the suction chamber and protrudes from said housing; a cylinder bore formed in said housing, said cylinder bore being located between the crank chamber and the first end of said drive shaft; a single-headed piston disposed in said cylinder, said piston being reciprocally movable therein; a cam plate mounted on and integrally rotating with said drive shaft in the crank chamber, said cam plate being operatively engaged with said piston, whereby rotational movement of said drive shaft is converted to reciprocating movement of said piston through said cam plate; and a shaft seal arranged between the suction chamber and the first end of said drive shaft, thereby sealing the suction chamber.
