A valve train is disclosed for an internal combustion engine having a block, a camshaft in the block, and at least two push rods actuated by the camshaft. The valve train comprises first and second rockers, and three valves. The first rocker is actuated by one of the push rods, and the second rocker is actuated by another of the push rods. A first valve is associated with a cylinder of the engine and actuated by the first rocker. A second valve is associated with the cylinder and actuated by the first rocker, and a third valve is associated with the cylinder and actuated by the second rocker.

A valve deactivator is provided that is capable of being activated and deactivated by a pulse energy input. The valve deactivator includes an input member and an output member which are movable relative to one another in the deactivated mode and which are engaged for simultaneous movement in an activated mode. A coil and armature, or other pulse energy input means, are provided to engage and disengage a locking system to activate and deactivate the valve actuator.

A connector is provided assembly for a north-south transaxle having a case and a solenoid assembly. The connector assembly includes a connector connected to a source of power and extending through an aperture in the case. The connector assembly also includes a structure for retaining the connector to the case to allow the solenoid assembly to be removed and installed without disturbing the connector.

The present invention is a method of adjusting backlash for a north-south transaxle. The method includes the steps of forming a case having a first passageway extending longitudinally and a second passageway spaced from the first passageway and being generally parallel to the first passageway and extending longitudinally and a cavity at one end of the second passageway having an opening generally perpendicular to the passageway. The method also includes disposing a transmission assembly in the first passageway and a transfer assembly in the second passageway and a differential assembly in the cavity and engaging the transfer assembly. The method further includes preloading the differential assembly, determining the amount of backlash between the differential assembly and transfer assembly, and adjusting the backlash between the differential assembly and transfer assembly.

The present invention is a filter assembly for filtering contaminants from first and second fluid sources. The filter assembly includes front and rear portions having front and rear apertures, respectively, extending therethrough. The filter assembly also includes a web portion for spacing longitudinally the front and rear portions and having a filter orifice extending therethrough for allowing fluid flow between the front and rear apertures. The front and rear portions include means forming a filter disposed in each of the front and rear apertures for filtering contaminants from fluid flowing through the front and rear apertures.

A pendulum absorber system attenuates torsional vibrations within a drive train of a vehicle. The system can be incorporated between an engine and an automatic transmission, for example, within a flex plate assembly attached to an engine's crankshaft, within a pump housing cover of a torque converter, or as a stand-alone unit between a flex plate assembly and a torque converter. The system includes at least one pendulum weight that dynamically moves along a predetermined path in response to variations in rotational velocities of a housing of the system and that is tuned to attenuate excitation of torsional vibrations within the drive train. A limiter assembly, which can include multiple limiters, is provided within the system for stopping movement of the weight when it reaches endpoints of the predetermined path, by mechanically impeding further movement at both of a first and second end of the weight.

An automatic transmission has a planetary gear set with a ratio controlling rotatable reaction element capable of either clockwise or counterclockwise rotation in accordance with different inputs to the gear set and resultant reactive torque loads applied thereto. A circular double acting brake band is used to selectively hold the reaction element stationary when desired and has opposite end portions that alternately serve as control application inputs or a grounding function. In one operative mode, a first end portion of the band receives an apply control force causing the second end portion to be grounded so that the band frictionally secures the reaction element from rotation in a first rotary direction and to thereby enable a first gear ratio. In another operative mode, the second end portion of the band receives an apply control force in direction opposite to the other apply force to cause the first end portion to be grounded so that the band frictionally secures the reaction element from rotation in a second rotary direction opposite the first rotary direction and to thereby enable a second gear ratio. With the brake band selectively activated from either end portion and anchored at the other end portion, the band is wrappingly energization about the reaction element in accordance with the direction of reaction torque thereon. The activation of the brake band is preferably by a hydraulic piston-operated band-locking lever with a pair of arm portions for selectively apply a force to either of the opposite end portions of the brake band.
