A swash plate type compressor comprising a plurality of cylinder bores and pistons, a swash plate chamber wherein a swash plate for reciprocating the pistons within the cylinder bores is fixed to and rotated with a drive shaft, at least one suction passage communicated with the swash plate chamber, suction chambers and exhaust chambers communicated with the cylinder bores, respectively. Two inlet ports open into the swash plate chamber so as to be opposed to a peripheral side surface of the swash plate when it is inclined to its utmost limit into a front side and a rear side in a predetermined longitudinal section of the compressor. The fluid sucked into the compressor is compressed therein with uniform volumetric efficiency without obstructed by the rotation of the swash plate.

A swash plate type compressor comprising: a pair of horizontal axially aligned cylinder blocks forming a combined block; a swash plate chamber perforated in the axially central portion of said combined block; a plurality of cylinder bores perforated in said combined block in the axial direction thereof; a plurality of pistons, each of said plurality of pistons being slidably inserted within each of said plurality of cylinder bores; a drive shaft disposed through said swash plate chamber and rotatably supported by said combined block in the axial portion thereof; a swash plate disposed within said swash plate chamber and fixed to said drive shaft so as to be rotated therewith, said swash plate being connected with said pistons through bearing balls and shoes so as to reciprocate said pistons within said cylinder bores due to the rotation of said swash plate; a pair of cylinder housing fixed to the ends of said combined block, one of said pair of cylinder housings having a shaft seal chamber in the axial portion thereof for accommodating a shaft seal member which is disposed around said drive shaft; at least one suction chamber and at least one exhaust chamber perforated in each of said pair of cylinder housings, said suction chamber and said exhaust chamber being communicated with each of said cylinder bores through valve means; at least one suction passage perforated in said combined block in the axial direction thereof between said cylinder bores adjacent to each other so as to be communicated with said swash plate chamber in the middle thereof; two inlet ports for introducing a fluid from an outer pipeline and at least one outlet port for discharging a compressed fluid into an outer pipeline; said two inlet ports being provided in said combined block so as to be aligned with each other in a longitudinal direction thereof; and said two inlet ports opening into said swash plate chamber directly so that each of the wall surfaces defining said two inlet ports in the side of the center of said swash plate chamber in said longitudinal section is nearly in alignment with an inner edge portion of said swash plate when said swash plate is inclined to the utmost limit thereof in a front side or a rear side of said combined block in said longitudinal section, and so that each of the wall surfaces which define said two inlet ports in the side of said cylinder housings in said longitudinal section, is deviated from an outer edge portion of said swash plate by a predetermined distance outside of said outer edge portion of said swash plate when said swash plate is inclined to the utmost limit thereof in a front side or a rear side of said combined block in said longitudinal section.
