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).


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 socket assembly is for a meter center including at least one meter having a stab. The socket assembly includes a base member; and a jaw assembly having a first jaw member and a second jaw member coupled to the first jaw member, each of the first jaw member and the second jaw member having a number of retaining edges and being structured to engage the stab. The jaw assembly is structured to rotate between a first position corresponding to disengagement between the number of retaining edges and the base member, and a second position corresponding to engagement between the number of retaining edges and the base member.


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 separator assembly is provided for, among other things, separating debris particles from a fluid in a fluid system. In an embodiment, the separator assembly may include a housing forming an internal chamber. An inlet port may be in communication with the internal chamber of the housing, and the inlet port can be oriented in a tangential relationship relative to the internal chamber. A first debris separation ring may be disposed in the housing and can extend around an inner surface of the internal chamber. A second debris separation ring can be disposed in the housing and can extend around the inner surface of the internal chamber, wherein the second debris separation ring may be spaced from the first debris separation ring.

An anti-rotation guide for a lifter in an overhead valve valvetrain. The anti-rotation guide includes a plug having two lobes connected through a neck region. A first lobe of the plug is held within a bore in the lifter. The bore forms an opening at the edge of the lifter through which the neck of the plug emerges. The bore in the lifter accommodates a first lobe of the plug that is wider than the opening in the edge of the lifter, whereby the plug is shaped to prevent its slipping from the lifter through the opening. The lifter reciprocates in a first bore in the cylinder head. The second lobe of the plug extends outward from the lifter into a second bore formed in the cylinder head and adjoining the first bore. The second lobe reciprocates in the second bore and limits rotation of the lifter.

A hydraulic lash adjuster (HLA) and an arrangement for a valve train assembly comprising an HLA are presented. A valve train component comprises a first body that defines a first bore. The HLA comprises a second body that defines a second bore and a plunger. In use, a first end of the plunger is mounted within the first bore, and a second end of the plunger is mounted within the second bore for reciprocal sliding movement with respect to the second body. The second body and the plunger define a first chamber for containing a hydraulic fluid and the plunger defines a second chamber for supplying hydraulic fluid to the first chamber through a valve located between the first and second chambers in response to movement of the plunger increasing the volume of the first chamber. In use, all of the second body is located outside of the first body.
