Abstract
Official abstract text for this publication.
A valve assembly may include a valve plate having an inlet hole through which working fluid passes from a vacuum muffler, a first discharge hole through which working fluid discharged from a cylinder passes, a second discharge hole through which the working fluid from the first discharge hole passes, and a pulsation and/or noise reducing passage through which the working fluid from the second discharge hole flows; a discharge valve at or in the valve plate configured to open and/or close the first discharge hole; a valve sheet having a first hole therein communicating with the first discharge hole and a second hole therein at an outlet of the pulsation and/or noise reducing passage; and a vacuum valve in the valve sheet configured to open and/or close the inlet hole.
First claim
