Capacity modulation system for compressor and method
US 8157538 B2
An apparatus is provided and may include a compression mechanism, a valve plate associated with the compression mechanism and having at least one port in fluid communication with the compression mechanism, and a manifold disposed adjacent to the valve plate. A cylinder may be formed in the manifold and a piston may be disposed within the manifold and may be movable relative to the manifold between a first position separated from the valve plate and a second position engaging the valve plate. A valve element may be disposed within the piston and may be movable relative to the piston and the manifold. The valve element may be movable between an open position spaced apart from the valve plate and permitting flow through the port and into the compression mechanism and a closed position engaging the valve plate and restricting flow through the port and into the compression mechanism.
36. The apparatus of claim 34, wherein said control mechanism selectively vents said chamber to allow said first pressurized fluid disposed within said seal chamber to move said piston from said second position to said first position.
This application claims the benefit of U.S. Provisional Application No. 60/951,274 filed on Jul. 23, 2007. The disclosure of the above application is incorporated herein by reference.
