タンデムポンプのオイル供給構造。 Gas is sucked into the cylinder chamber by means of a plurality of piston members that are slidably brought into contact with the outer periphery of a swash plate that is fixed to a rotating shaft and rotates, and that are reciprocated as the swash plate rotates. , a tandem pump in which a swash plate type piston pump for compressing and discharging and another gas pump that rotates around the same rotation axis are provided in an integrated housing, and an oil flow path for lubrication is provided inside the pump during rotation. The oil flow path communicates with the oil supply path, and the oil flow path includes an oil circulation path leading to the abutting portion between the piston member and the swash plate of the swash plate type piston pump, and the above-mentioned others. An oil supply structure for a tandem pump, characterized in that an oil circulation path of a gas pump is branched and communicated with the oil circulation path of the gas pump.
