SWASH PLATE COMPRESSOR

WIPO Patent Application WO/2010/068026

A2

A swash plate compressor of the present invention includes: a housing; a cylinder block including a plurality of cylinder bores; a piston that is accepted and reciprocates in the cylinder bore respectively; a drive shaft that is inserted in a coupling hole formed on the cylinder block and is installed to be rotatable; a swash plate that is placed in a swash plate chamber between the housing and the cylinder block and is coupled to the drive shaft at an oblique angle; a rotary valve that is formed on on a portion of the drive shaft with the coupling hole and is formed with a coolant outlet hole passing through along the circumferential direction; and a connection hole that allows connection with the cylinder bore by being formed on the cylinder block and connects with the coolant outlet hole periodically as the rotary valve rotates, wherein the piston includes a flow passage connecting the connection hole with the swash plate chamber. The swash plate compressor of the present invention enables quick inflow of the coolant into the cylinder bore during the intake stroke of the piston, by forming the flow passage on the piston that enables the piston to connect with an intake passage and the swash plate chamber to prevent the coolant from remaining in the intake passage after completing the compression stroke.
