Abstract: A system. The system includes a prelubrication system, a filtration system, a valve, a sensor and a control module. An inlet of the valve shares a common junction with an outlet of a component of the prelubrication system and an inlet of a component of the filtration system. The sensor is configured to detect a triggering condition. The control module is coupled to the valve, and is configured to control operation of the valve based on the detected triggering condition.

Abstract: A fluid filtration apparatus. The fluid filtration apparatus includes a pump, a filter apparatus and a valve assembly. An inlet of the valve assembly shares a common junction with an outlet of the pump and an inlet of the filter apparatus. The fluid filtration apparatus further includes a sensor configured to detect a filter triggering condition and a control module coupled to the sensor and the valve assembly. The control module is configured to control operation of the pump based on the detected filter triggering condition.

Abstract: Enhanced fluid filtration methods, systems, and techniques are disclosed that can leverage the function of a supplemental pump in combination with the existing components of a machine, such as the main pump of an electrically-powered machine with an engine. In various embodiments, a supplemental filter apparatus may be operatively associated with the supplemental pump to provide filtration of fluid flowing through the machine. A control module may be operatively associated with the supplemental pump and/or various components of the machine. The control module may be programmed to activate or deactivate the supplemental pump, a valve, or take other actions in association with detecting the existence of one or more filter triggering conditions.

Abstract: An engine pump is provided which operates with an internal combustion engine or as a supplemental pump or as used in a stand alone device, and includes an internal vent for improved pump and motor durability. The pump is operably and sealably connected to a motor and adapted for connection with a source of fluid and a discharge means. An internal vent is positioned in between an armature shaft of bore along an inlet port thereby decreasing the pressure in the area of the seal. Alternatively, a valve is positioned between the inlet and outlet ports to selectively permit fluid pumped between the inlet and outlet ports to pass through when the outlet port is flow restricted.

Abstract: An engine prelubrication pump includes a pump housing with a pump cavity in which a first and second gear are positioned for pumping fluid. The first gear is operably and sealably connected to a motor for rotation and the second gear is rotatably mounted to a second shaft for geared rotation with the first gear. Fluid inlet and outlet ports are located in communication with the pump cavity and adapted respectively for connection with a source of fluid and a discharge means and an internal vent is positioned in between the armature shaft of bore and the pump housing along the inlet port. Alternatively, a valve is positioned between the inlet and outlet ports to selectively permit fluid pumped between the inlet and outlet ports to pass through when the outlet port is flow restricted.

Abstract: A viscosity sensitive, pressure divider arrangement for use as part of an engine timing control tappet system where that system includes a block oil pressure supply, hydromechanical control valve and an oil sump, the pressure divider arrangement including an inlet chamber, a divider chamber and an exit chamber. The inlet chamber is connected to the divider chamber by means of a first connecting conduit having a relatively short length. The outlet side of the divider chamber is connected with the exit chamber by means of a second connecting conduit which has a length substantially longer than the length of the first connecting conduit. Additionally, the divider chamber includes a pressure-assist outlet aperture which is in flow communication with the hydromechanical control valve. The viscosity of oil flowing into the pressure divider arrangement will be acted upon by the combination of connecting conduits wherein the first connecting conduit is less viscosity sensitive than is the second connecting conduit.
