Claims

[Scope of utility model registration request]

a rotating drive shaft; a swash plate tilted and fixed to the drive shaft;
Dual cylinders are formed to face each end face of the swash plate and parallel to the drive shaft, and are fitted into each cylinder so as to be able to reciprocate, and are in constant sliding contact with each end face of the swash plate. each piston, a lubricating oil pump provided at one end of the drive shaft, a main oil supply passage formed within the drive shaft and having one end communicating with the lubricating oil pump, and a main oil supply path formed on the drive shaft,
A swash plate type compressor comprising a first oil supply passage and a second oil supply passage, each of which has one end communicating with the main oil supply passage and whose other end communicates with each space adjacent to each end face of the swash plate, The cross-sectional area of the connection point between the first oil supply path and the main oil supply path located on the upstream side of the main oil supply path is set to be larger than the cross-sectional area of the connection point with the main oil supply path of the second oil supply path on the downstream side. Characteristic swash plate compressor.
