Title:
ONE-WAY VALVE AND SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/128793
Kind Code:
A1
Abstract:
A one-way valve and a scroll compressor. The one-way valve (200) comprises: a valve plate (210) on which a valve opening (212) for a fluid to pass is provided; a valve reed (220) arranged above the valve plate (210) and constructed to selectively close or open the valve opening (212); and a vibration reduction component (250) arranged below the valve reed (220) and constructed to generate elastic deformation under the action of the force of the valve reed (220) during the process that the valve reed (220) closes the valve opening, so as to at least partially absorb vibration energy from the valve reed (220). The one-way valve (200) is provided at an air outlet (11) of a non-orbiting scroll member (10) of the scroll compressor. The structural configuration of the vibration reduction component can damp and absorb the vibration energy of the valve reed, and reduces the vibration noise of the valve reed and the overall noise level of the scroll compressor comprising the one-way valve.
