Patent number: 8677742Abstract: An accumulator includes a canister, a piston, a sleeve, and a solenoid control valve assembly. The canister has an inner surface that defines an interior volume. The piston is slidably disposed within the interior volume of the canister. The piston is located between the inner surface of the canister and an outer surface of the sleeve. The piston divides the interior space into a fluid filled chamber and an air filled chamber. A fluid pathway is created by an outer surface of the sleeve and the inner surface of the canister. The fluid pathway allows fluid from an exterior source to either enter or exit the fluid chamber. The solenoid control valve assembly includes a valve body, a valve biasing member, and a plunger that is slidable within a recess of the valve body.Type: GrantFiled: February 1, 2011Date of Patent: March 25, 2014Assignee: GM Global Technology Operations LLCInventors: Leonid Basin, Fredrick R.

Patent number: 8433485Abstract: A torque sensor system for a transmission and other powertrain components in a motor vehicle includes a receiver and a transmitter. The receiver is operable to induce and detect a signal from the transmitter that is indicative of a torque load on the transmitter. The receiver is cylindrical and has an outer surface with a maximum, constant diameter. The outer surface defines one or more fluid transfer grooves and a docking port for an electrical connection. The fluid transfer groove and the docking port do not extend beyond the maximum outer diameter of the outer surface. Therefore, the receiver is capable of being press-fit within a component and is capable of routing fluid flow.Type: GrantFiled: November 18, 2011Date of Patent: April 30, 2013Assignee: GM Global Technology Operations LLCInventors: Carlos E.

Patent number: 8202195Abstract: The pinion gear assembly thus includes a first and a second pinion gear arranged with generally parallel axes of rotation. A first and a second washer, referred to herein as stationary washers, are provided. Each of the washers has two openings spaced to generally align with two predetermined, spaced mounting locations on the planet carrier member. The first and the second washers are positioned on opposing sides of the first and second pinion gears, with the axes of rotation of the first and second pinion gears generally centered at the respective spaced openings of the washers. Because the stationary washer spans the two pinion gears, which are secured to the carrier member, the stationary member is operatively connected at two locations to the carrier member, eliminating the need for anti-rotation features and corresponding carrier features.Type: GrantFiled: May 6, 2009Date of Patent: June 19, 2012Assignee: GM Global Technology Operations LLCInventors: Fredrick R. Poskie, Boris Burgman
