Abstract: A heat isolating linkage (5) that includes an elongate link having first and second end portions (10, 12) and a middle portion (14) extending therebetween. A bearing opening (16) is formed in the first end portion (10) and a bearing race (18) is disposed in the bearing opening (16). A rod end ball (20) is disposed in the bearing race (18). At least one aperture (30-36) is formed through the middle portion (14). The middle portion (14) may include a plurality of apertures (30-36) each in the form of a rectangle that forms a ladder pattern. Accordingly, the middle portion (14) has a cross sectional area (A2) that is smaller than the cross sectional area of at least one of the first and second end portions (A1, A3).

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 system for controlling movement of an actuator includes an input power source that provides an input pulse width (PWM) signal; a motor driver that receives the PWM signal and provides a synthesized three-phase drive signal; a brushless direct current (BLDC) motor that receives the drive signal and operates in response to the received drive signal to reposition the actuator; and a controller that receives the PWM signal. The controller includes an amplitude detection module that detects the amplitude of the PWM signal, and a direction detection module that detects the polarity of the PWM signal.

Abstract: Turbochargers use actuators to control wastegate valve or VTG vane position to control turbine wheel power. Components of such actuators are susceptible to damage when exposed to foreign liquids, solids and debris. To prevent such ingress, boot seals at the actuator shaft can provide a tortuous path for air aspiration and expulsion from the volume inside the actuator boot is provided at one or more interfaces in the actuator system. Such a path can also prevent ingress of undesired liquids, solid and debris, which can affect actuator performance material. In one arrangement, a tortuous pathway is provided between a boot seal holder and another actuator component. In another arrangement, a tortuous pathway is provided between the actuator shaft and an end portion of a boot seal.
