Fluid Machine |
| 摘要 |
An object of the invention is to provide a fluid machine capable of reducing vibration of a discharge valve while reducing a delay of closing of the discharge valve. The invention provides “a fluid machine, including: a piston reciprocating in a cylinder; a valve seat plate provided in the cylinder; a valve provided to a port portion of the valve seat plate and opening and closing in accordance with reciprocation of the piston; and a valve retainer for regulating an opening amount of the valve, wherein a surface of the valve retainer, the surface facing the valve seat plate, is inclined above the port portion so that an open end side is closer to the port portion and has a part farthest from the valve seat plate between the port portion and the fixed end”. |
