CYLINDER-ROTATION-TYPE COMPRESSOR

摘要

A cylinder-rotation-type compressor includes a discharge valve that is disposed in a cylinder and configured by a reed valve, a valve body portion that closes a discharge hole provided in the cylinder, and a support portion that couples the valve body portion with a fixing portion fixed to the cylinder. A shape of the valve body portion and a shape of the support portion are substantially symmetrical with respect to a line segment extending in a radial direction of a rotating axis. The valve body portion is disposed on a radially outer side of a connection portion of the fixing portion and the support portion.

1. A cylinder-rotation-type compressor comprising:
a rotatable cylinder that includes a cylindrical member which extends in an axial direction of a rotating axis, and a closing member which closes an end of the cylindrical member in the axial direction; a columnar member which is housed inside the cylinder and extends in the axial direction of the rotating axis of the cylinder; and a partition member which is slidably fitted into a groove portion provided in one of the cylinder and the columnar member, and partitions a compression chamber provided between the cylinder and the columnar member, wherein the closing member includes a discharge hole through which a fluid compressed in the compression chamber flows out of the compression chamber, the cylinder-rotation-type compressor further comprising a discharge valve that limits backward flow of the fluid into the compression chamber through the discharge hole, the discharge valve is a plate-shaped member, and includes a valve body portion that closes the discharge hole, a fixing portion that is fixed to the cylinder, and a support portion that couples the valve body portion with the fixing portion, a shape of the valve body portion and a shape of the support portion are substantially symmetrical with respect to a line segment extending in a radial direction of the rotating axis when viewed from the axial direction of the rotating axis, and the valve body portion is disposed on a radially outer side of a connection portion connecting the fixing portion and the support portion.
