Title:
SWASH PLATE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2010/068025
Kind Code:
A2
Abstract:
A swash plate compressor of the present invention includes: a housing; a cylinder block that has a plurality of cylinder bores and is coupled to the housing; a piston that is accepted and reciprocates in the cylinder bores respectively; a drive shaft that is installed to be rotatable with respect to the housing and the cylinder block; a swash plate that is rotated by the drive shaft and connected to the piston; a valve plate that is placed between the housing and the cylinder block; and a rotary valve that rotates with the drive shaft and is installed and allows the rotation thereof on the inner plane of a coupling hole formed in the cylinder block. The swash plate compressor of the present invention further comprises: a coolant suction hole formed on the cylinder block to communicate with a swash plate chamber and a coolant storage chamber of the housing; a coolant inflow hole formed on the drive shaft and communicating with the coolant storage chamber; a coolant outflow hole formed on the rotary valve and communicating with the coolant inflow hole; and a communication hole formed on an inner peripheral of the coupling hole that contacts the coolant outflow hole and communicates with the cylinder bores. As the coolant inflow hole through which coolant in the swash plate flows in is formed together inside the coupling hole of the cylinder block, the coolant can flow in stably regardless of torque of the drive shaft that rotates at high speed. As a result, the present invention has an advantage of reducing loss caused by the coolant inflow resistance.
