Title:
SWASH PLATE COMPRESSOR WITH ROTARY VALVE
Document Type and Number:
WIPO Patent Application WO/2010/058998
Kind Code:
A3
Abstract:
The present invention relates to a swash plate compressor with a rotary valve which can effectively siphon a coolant into a swash plate chamber through a cylinder block. The swash plate compressor comprises a housing connected to the cylinder block which has a plurality of cylinder bores, pistons which are accommodated and reciprocate in the respective cylinder bores, a drive shaft which is installed to rotate with respect to the housing and the cylinder block, a swash plate which is installed to be rotated by the drive shaft and interlock with the pistons, a valve plate which is interposed between the housing and the cylinder block, and the rotary valve which is formed to rotate along with the drive shaft and installed to roll in a joint hole formed in the cylinder block. A coolant outlet is formed on the exterior of the rotary valve, connection holes connected to the respective cylinder bores are formed on the interior of the joint hole which abuts against the exterior of the rotary valve, and a coolant inlet groove is formed to penetrate the swash plate chamber through to the housing. Therefore, loss caused by coolant inlet resistance can be remarkably reduced by siphoning coolant regardless of the torque of the drive shaft rotating at high speed.
