A method for setting lash on a switching rocker arm assembly includes providing a rocker arm having (i) an outer arm having a first outer side arm and a second outer side arm, the outer arm defining an opening, (ii) an inner arm disposed between the first and second outer side arms, (iii) a roller follower that selectively engages a cam, the roller follower mounted about a bearing axle that extends through the opening. A zero lash shim is inserted into a gap defined between the bearing axle and the outer arm at the opening. The rocker arm is installed into the valvetrain with the master tip cap. Lash is measured between the cam and the roller follower. The rocker arm and the master tip cap is removed. A select fit valve tip cap is installed based on the master tip cap and the measured lash.

A switch includes a switch housing, a button, a circuit board having at least one magnet sensor, and a magnet holder, including at least one magnet, movably mounted to the housing to move responsive to an actuation of the button. A vane interrupter in the switch includes a passage structure positioned proximate to each magnet sensor such that a respective magnet is movable at least partially within a passage defined by the passage structure, and a flange structure having a first flange and a second flange positioned on opposing ends of the passage structure, with the first flange positioned adjacent a portion of the magnet holder holding the magnet and with the second flange positioned adjacent a surface of the circuit board opposite a surface on which the at least one magnet sensor is positioned, such that the circuit board is positioned between the magnet holder and the second flange.


A system for selectively deactivating engine valves of a cylinder of an internal combustion engine. The system employs switching rocker assemblies between the valves of the engine and rotating cam lobes. The disclosed design is able to operate using a single cam lobe per valve. The rocker assembly employs a first arm pivotally attached to a second arm at one end. The first arm engages the valve and the second arm has a roller bearing that engages the cam lobe. A latch causes the first and second arm to move in unison following the cam surface when latched. When unlatched, the second arm follows and moves according to the rotating cam surface, but the first arm does not follow and does not actuate the valve, thereby deactivating the cylinder.

A gear hobbing apparatus for producing a gear from a blank according to one example of the present disclosure can include a hob, a first series of hob teeth and a second series of hob teeth. The hob can have a cylindrical hob body. The first series of hob teeth can extend from the cylindrical hob body and have a first whole depth. The second series of hob teeth can alternately extend from the cylindrical hob body with the first series of hob teeth and have a second whole depth. The first and second whole depths are distinct and configured to create a gear from the blank that has adjacent teeth having distinct outer diameters.

A multi-stage centrifugal pump assembly allows for multiple fixed ratio pressure levels. The multiple pressure levels permit optimization of actuation loops without the need for pressure regulators, and can be used directly by the actuators.


An apparatus includes a magnetizing circuit configured to be coupled to a transformer and to selectively provide a magnetizing current to the transformer and a control circuit configured to cause the magnetizing circuit to provide the magnetizing current following disconnection of the primary winding of the transformer from the power source. The magnetizing circuit may be configured to provide the magnetizing current from a first source following disconnection of the primary winding from a second source. The transformer may include a first transformer and the apparatus may further include a second, higher impedance transformer coupled between the second source and the first transformer. In further embodiments, the magnetizing circuit may include a solid-state converter.

The present disclosure provides an improved, integrated electronically controlled hydraulic-based torque distribution system and related method. The torque distribution system of the present disclosure includes an electric motor that drives a pump that generates hydraulic pressure used to selectively activate a clutch pack to transfer torque to the wheels of a motor vehicle.


An energy conserving hydraulic system for a mobile work machine includes a prime mover, a drivetrain, a baseline hydraulic system, a power-take-off, a transformer, a work implement, and an accumulator. The drivetrain may include an automated manual transmission (AMT) that is rotationally coupled to the prime mover and the power-take-off. The baseline hydraulic system is powered by the prime mover and includes a first hydraulic circuit. The transformer is hydraulically coupled to second and third hydraulic circuits. The work implement is actuated by an actuator that is adapted to be simultaneously hydraulically coupled to the first and the second hydraulic circuits. The power-take-off is adapted to exchange shaft power with the transmission. A clutch selectively rotationally couples the transmission and the power-take-off. The accumulator is hydraulically coupled to the second hydraulic circuit. The second hydraulic circuit is hydraulically coupled to a first rotating group of the hydraulic transformer, and a third hydraulic circuit is hydraulically coupled to a second rotating group of the hydraulic transformer.

A linear actuator assembly (200,200,200) is for an electrical switching apparatus (100,100,100), such as a multi-pole circuit breaker. The circuit breaker includes a plurality of pole units (102,104,106;102,104,106,102,104,106) each having separable contacts (110). The linear actuator assembly (200,200,200) includes a base unit (202,202,202) comprising a housing (204,204,204), and a plurality of linear actuators (302,304,306;302,304,306;302,304,306). Each linear actuator (302,304,306;302,304,306;302,304,306) is mounted within the housing (204,204,204) in alignment with a corresponding one of the pole units (102,104,106;102,104,106;102,104,106). Each linear actuator (302,304,306;302,304,306;302,304,306) actuates the separable contacts (110) of the corresponding one of the pole units (102,104,106;102,104,106;102,104,106). A controller (402) is adapted to control actuation of the linear actuators (302,304,306;302,304,306;302,304,306).
