Реферат: A wastegate valve (34) for a turbocharger includes a ball-type valve member (35), which is movable relative to a valve seat (37), and a spring-biased piston (57). A valve spring (52) biases the valve member (35) toward the closed position in engagement with the valve seat (37). The piston (57) also biases the valve member (35) to the closed position. While the piston (57) normally closes the valve member (35), a pressure source is operable to selectively drive the piston (57) away from the valve member (35) so that the valve member (35) is acted upon solely by the valve spring (52). The valve spring (52) is set such that exhaust gas pressure can open the waste gate valve (34) and allow self-compensating adjustment in response to exhaust gas pressure.
