ABSTRACT:
A piston-type compressor has a compressor housing enclosing a crank chamber, suction chamber, and a discharge chamber. The compressor housing also includes a cylinder block having at least two cylinders. A single head-type piston is slidably disposed within each of the cylinders. A drive shaft is rotatably supported in the cylinder block. A plate is tiltably connected to the drive shaft. A bearing couples the plate to the pistons, so that the pistons are driven in a reciprocating motion within the cylinders upon rotation of the plate. A piston guiding mechanism has a first guiding device which is formed on the peripheral of the piston, and a second guiding device which is disposed within the housing for guiding the first guiding device to slide smoothly along the second guiding device and to prevent the piston from rotating around its axis or radially inclining when the piston reciprocates in the cylinder. Thus, the movement of a piston during reciprocating is carefully regulated, and the durability of the compressor increases.
