초록 ▼

A start control for a compressor has an air inlet valve for reducing flow intake when a compressor is started. The valve has a housing with an inlet and an outlet which is connected to a compressor. A rod in the housing is movable relative to the housing and has a shoulder and a piston. A movable plate is mounted on the rod and a spring is interposed between the plate and the housing for biasing the plate toward a closed position in which the housing inlet is at least partially closed. A second spring is interposed between the piston and the housing for moving the shoulder into engagement with the plate and biasing the plate toward the closed position. The housing has a chamber on each side of the piston for receiving air that discharges from the compressor. Air pressure applied to one side of the piston assists the first spring and the second spring move the plate toward the closed position when the compressor is in a start mode of operation. Air pressure applied to a second side of the piston opposes the second spring and reduces bias on the plate whereby the plate is permitted to move away from the closed position when the compressor is in a run mode of operation.

A valve for controlling flow to a compressor, comprising: a housing having an inlet, and an outlet connected to a compressor; a rod in the housing a shoulder on the rod; means for mounting the rod for movement relative to the housing; a plate movable along the rod; a first spring between the plate and the housing for biasing the plate toward a closed position in which the housing inlet is at least partially closed; a piston on the rod, said piston having opposed sides; a second spring between the piston and the housing for moving the shoulder into engagement with the plate and biasing the plate toward said closed position; a chamber in the housing on one of said piston sides for receiving air discharged by the compressor, said air having a pressure that acts against the piston and assists the first spring and the second spring move the plate toward the closed position when the compressor is in a start mode of operation; and a chamber in the housing on the other said piston sides for receiving air discharged by the compressor, said air having a pressure that acts against the piston in opposition to the second spring and reduces bias on the plate whereby the plate is permitted to move away from the closed position when the compressor is in a run mode of operation.
