Title:
COMPRESSOR VALVE PLATE
Document Type and Number:
WIPO Patent Application WO/2010/058564
Kind Code:
A1
Abstract:
Provided is a specific structure for a compressor valve plate, which can ensure smooth operation of an intake valve in terms of intake valve adhesion force by using lubricant oil, and can be mass-produced at low cost with high efficiency. The compressor valve plate comprises: a valve plate having an intake hole and a discharge hole; an intake valve; and a discharge valve. The valve plate constitutes at least one part of a gas filling chamber which may be filled by introducing gas at a higher pressure than intake gas pressure between the valve plate and the intake valve, while a communication hole communicating with a surface at the closed side of the intake valve is formed. The discharge valve which comprises a thin plate is formed in at least one part of a gas introduction path for introducing the high-pressure gas into the communication hole. In addition, the one part of the gas introduction path where the discharge valve is formed is sealed by means of a member disposed on the surface facing the discharge valve.
