Abstract
A two-step metering device for controlling the flow of an operating fluid to a variable capacity compressor is provided. The metering device includes a valve that defines a fluid flow path having a large orifice configured to allow a flow rate corresponding to a high operating capacity of the compressor and a small orifice configured to allow a flow rate corresponding to a reduced operating capacity of the compressor. The metering device further includes a control operable to adjust the valve to direct the operating fluid through the large orifice when the compressor is operating at the high capacity and to direct fluid through the small orifice when the compressor is operating at the reduced capacity.
