Abstract
A damping apparatus for an exhaust valve in a compressor, an exhaust valve assembly having the damping apparatus, and a compressor using the exhaust valve assembly. The damping apparatus comprises a fixed body; the fixed body comprises an exhaust hole comprises an exhaust hole through which a compression cavity and an exhaust cavity are in fluid communication with each other; the exhaust hole comprises an inlet, an outlet, and an intermediate cavity provided between the inlet and the outlet and allowing the inlet and the outlet to be in fluid communication with each other; the intermediate cavity is configured to enable the backflow of the gas from the exhaust cavity to form a vortex in the intermediate cavity. The damping apparatus has advantages of reducing the force and frequency of impacts on an exhaust valve plate, and prolonging the service life of the valve plate.
