Abstract: A pump actuator for use between a cam and a pump comprises a pump actuator body having a pad defined between a plunger facing surface and an opposite roller facing surface, where the plunger facing surface is recessed into the pump actuator body and offset from a radial end. The pump actuator body further comprises a cylindrical wall defined between the radial end and the plunger facing surface. A concave surface feature is formed on the pad on its plunger facing surface. The opposite roller facing surface of the pad is provided with a surface enhancing treatment comprising shot peening. These features, separately or in combination, provide mass-neutral improvements of the pump actuator body's fatigue life.

Abstract: When selecting cylinders of a multi-cylinder diesel engine in an engine system for cylinder deactivation (CDA), a method can comprise designating a first resonance around a first periodic frequency output of the engine system as a primary boundary and designating a second resonance around a second periodic frequency output of the engine system as a secondary boundary. Selecting cylinders can comprise selecting one of half, one third, or two thirds of the multiple cylinders for CDA while firing the remaining multiple cylinders. The selection can be made so that the periodic frequency output of the engine is between the primary and secondary boundaries. A compact periodic frequency band can be implemented to further restrict the selection of cylinders for CDA. The first periodic frequency output can be about 15 Hertz+/−1.5 Hertz and the second periodic frequency output can be between 30-40 Hertz+/−1.5 Hertz.

Abstract: The invention provides a connector system for use in a power distribution system, which can be found in a motor vehicle, and includes features that increase the safety, durability and reliability of the connector system and the power distribution system. The connector system includes a female connector assembly with a female housing, a female terminal assembly that is inserted into the female housing using a first force, and a touchproof member inserted into the female terminal assembly using a second force oriented opposite the first force. The touch-proof member prevents insertion of a foreign object into the female terminal assembly. The connector system also includes a male connector assembly with a male terminal assembly, and a male housing assembly with a touch-proof element opening that receives an extent of the touch-proof member. The male terminal assembly includes a male terminal body with contact arms having a neck portion with a neck width and a body portion with a body width that is greater than the neck width. The male terminal assembly also includes a spring member that resides within a receiver of the male terminal body, wherein during operation of the power distribution system, spring arms of the spring member apply an outwardly directed biasing force on the contact arms.

Abstract: Embodiments of the present disclosure provide medium or high voltage fuses that employ spiral wound elements supported by rods, which may replace the usages of a ceramic core. In particular, the use of rods to wind and fix spiral fuse elements provides increased reliability by minimizing the fuse elements from drifting within the fuse assembly.

Abstract: A switch disconnector comprises an electrical contact system for breaking a circuit connectable to the switch and a ferromagnetic plate being positioned in a predefined distance to the electric contact system, wherein the predefined distance is selected such that the magnetizing force of the ferromagnetic plate on an electric arc occurring between separated contacts of the electric contact system pulls the arc onto the ferromagnetic plate for interruption of the arc.

Abstract: A method for identification of a power supply source, a power supply system and a system having at least one load is disclosed. The at least one load receives power from the power supply system and makes measurements of the AC output signal of the power supply source. A supervisory device operatively coupled to the at least one load is disclosed. The supervisory device receives measurements from the at least one load and determines an identification of the power supply source of the power supply system by demodulating and decoding the received measurements.
