Abstract
A lubricating structure in a piston type compressor has a housing, a device for being lubricated and a rotary shaft. The housing defines an accommodating chamber and a suction pressure region. The device for being lubricated is located in the accommodating chamber. The rotary shaft is rotatably supported by the housing. The rotary shaft includes a supply passage, a communicating port, a lubricating hole and a flow guiding portion. The supply passage transfers fluid that contains lubricant. The communicating port interconnects the supply passage and the suction pressure region. The lubricating hole interconnects the accommodating chamber and the supply passage. The flow guiding portion is formed on a circumferential surface of the supply passage and is located near the lubricating hole. The flow guiding portion guides the lubricant toward the lubricating hole.
