Abstract
A piston for use in a compressor that compresses gas containing lubricating oil is disclosed. The compressor has a crank chamber and cylinder bores for accommodating the pistons. A swash plate is located in the crank chamber and is supported on a drive shaft for integrally rotating with the drive shaft. The swash plate is operably connected to the pistons by shoes to convert the rotation of the drive shaft to reciprocation of each piston. Each piston has a head for compressing the gas supplied to the cylinder bore and a skirt projecting from the head toward the crank chamber. The skirt has a slot for receiving the swash plate by means of the shoes. A rib is formed on an inner wall of the slot and extends parallel to the axis of the piston. When the swash plate rotates, swirling gas in the crank chamber collides against the rib. When the gas collides against the rib, the oil contained in the gas separates from the gas and is guided to the shoes.
