Abstract:
A compressor with a pulsation pressure reducing structure, comprising:a cylinder block provided with a plurality of bores radially arranged for a plurality of pistons to be movably inserted therein; a front housing positioned in front of said cylinder block to define a crank chamber that communicates with the bores of said cylinder block; a rear housing positioned in the rear side of said cylinder block; a valve plate positioned between said cylinder block and said rear housing, said valve plate having a plurality of suction holes and discharge holes whose respective number is same as that of said bores; a suction reed valve positioned in front of said valve plate for opening said suction holes; a discharge reed valve positioned in the rear side of said valve plate for opening said discharge holes; wherein, said rear housing providing a suction chamber and a discharge chamber that communicate with said plurality of bores through said plurality of suction holes and said plurality of discharge holes in such a manner to be separated from each other, on the rear side of said cylinder block, and providing a suction pipe passage that communicates with said suction chamber and a discharge pipe passage that communicates with said discharge chamber through at least two discharge holes separated from each other relative to said plurality of discharge holes of said valve plate; a driving shaft adapted to be extended through said front housing in such a manner as to be disposed on the center of said crank chamber in a longitudinal direction of said cylinder block and supported by means of said front housing; a lug plate adapted to be fixedly attached around said driving shaft of said crank chamber and rotated by said driving shaft; a swash plate adapted to be slantly fitted around said driving shaft and hingedly attached to said lug plate to be rotated together by said lug plate; and a plurality of pistons adapted to be engaged with the outer periphery of said swash plate to perform reciprocating movement within the bores of said cylinder block by wobbling of an outer periphery of said swash plate in the forward and backward directions according to the rotation of said driving shaft.
