摘要： There is provided a compressor including: a piston that reciprocates inside a cylinder; a valve plate that closes an end portion of the cylinder; a connecting rod that supports the piston; a crankshaft that applies a rotating force to an end portion of the connecting rod; and a crankcase that rotatably supports the crankshaft. The piston is an oscillating piston that reciprocates while oscillating inside the cylinder according to rotation of the crankshaft. An outer peripheral surface of the piston is a curved surface.

摘要： There is provided a compressor including: a piston that reciprocates inside a cylinder; a valve plate that closes an end portion of the cylinder; a connecting rod that supports the piston; a crankshaft that applies a rotating force to an end portion of the connecting rod; and a crankcase that rotatably supports the crankshaft. The piston is an oscillating piston that reciprocates while oscillating inside the cylinder according to rotation of the crankshaft. A central axis of an inner diameter of the cylinder is disposed at a position shifted by an offset amount e with respect to a rotation center axis of the crankshaft. An upper surface of the piston is substantially parallel to a crankcase side surface of the valve plate in a state where the piston is at a top dead center.
