VARIABLE FLOW VALVE FOR TURBOCHARGERS |
摘要 |
A variable flow valve with position feedback is disclosed. The variable flow valve includes a housing having an inlet port and a discharge port and one or more control ports, and also includes a piston connected to a primary valve to open and close fluid communication between an inlet port and a discharge port of the housing. The housing and the piston intermesh to define an inner chamber and an outer chamber each in fluid communication with its own control port. A control port valve opens and closes at least one of the control ports to control access to a source of pressure change. A position sensor is part of the position feedback and communicates the position of the primary valve, relative to the discharge port, to a controller that operates the control port valve to hold the primary valve in a position where the discharge port is partially open. |
