Abstract: A product may include a canister and a diaphragm may separate a control chamber within the canister. A piston may be movable in the canister between a first position and a second position in response to a pressure change in the control chamber. The piston may have a body and a skirt may extend from the body. The skirt may taper inward relative to the body as the skirt extends away from the body.

Abstract: A variable position device (25) for a turbocharger includes a turbine wheel (24). A fluid diverter (26) for diverting exhaust gas flow to the turbine wheel (24) is moveable inclusively between a first and a second end-stop position (80, 104, 82, 106) defining an end-stop span (84, 108). An actuator (46) is in operable association with the fluid diverter (26). The actuator (46) is configure to, in an operation mode, selectively move the fluid diverter (26) inclusively between a first and a second guard band position (88, 110, 90, 112) defining a guard band span (92, 114) that is less than the end-stop span (84, 108). The actuator (46) is configured to, in a first mode, move the fluid diverter (26) to a first reduced guard band position (94, 116) that is inclusively between the first end-stop position (80, 104) and the first guard band position (88, 110), and apply a constant force to the fluid diverter (26) to hold the fluid diverter (26) in the first reduced guard band position (94, 116).
