Abstract: A system including an engine block and a crankshaft able to rotate around axis A, and a pump with an impeller, the impeller mounted coaxially to the crankshaft such that the crankshaft drives the impeller. The system can be part of an engine for a vehicle, and the pump can drive water or other coolant through the engine.

Abstract: A material processing apparatus has as a power supply system comprising an electrical power supply and a hydraulic power supply. The electrical power supply comprises a battery pack and an electrical generator. The power supply system is operable in different power supply modes in which said at least one battery and/or said electrical generator supply electrical power to the electrically powered components of the system.

Abstract: An internal combustion engine is provided, including at least one cylinder head including a water pump that is cast into the cylinder head housing.

Abstract: A fan adapter includes a base and a fan end portion. The base includes a mounting portion and a coupling portion, and the base is configured to be coupled to a portion of an engine. The fan end portion includes a mounting portion and a coupling portion. The coupling portion of the fan end portion is configured to be coupled to the coupling portion of the base, and the fan end portion is removably couplable to the base via one or more coupling elements to prevent relative rotation between the base and the fan end portion.

Abstract: A hand-held power tool includes an electrical motor unit which includes a stator and a rotor arranged concentrically outside the stator, wherein a heat pipe is arranged with a first end inside the stator, thermally connected to the stator, and a second end reaching outside of the stator and thermally connected to a cooling device having a heat sink for cooling the second end of the heat pipe. The heat pipe includes a phase changing fluid for transporting heat from the first end to the second end to be dissipated at the cooling device. A fan is arranged to provide a cooling air stream to the heat sink and the fan is arranged to provide a cooling air stream to the heat sink independently of an operation of the motor unit.

Abstract: A hub for a fluid-flow control system of a vehicle can include an interface surface configured to be positioned adjacent to a corresponding interface surface of the fluid-flow control system. The interface surface can have at least two openings positioned to align with at least two corresponding openings in the corresponding interface surface of the fluid-flow control system and through which mounting components are receivable for coupling the hub to the fluid-flow control system. The hub can also include a raised surface protruding from the interface surface and having a diameter that is smaller than another diameter of the interface surface. The raised surface can have a profile with at least two keys configured to be received in corresponding keyholes of the corresponding interface surface of the fluid-flow control system.

Abstract: A heat exchanger includes a first half defining a first inlet portion and a first outlet portion, a second half defining a second inlet portion and a second outlet portion. The first half and the second half are configured to mate and form an inlet chamber and an outlet chamber. At least one of the first half or the second half includes one or more inlet transfer holes defined through a thickness of at least one of the first inlet portion and/or the second inlet portion. At least one of the first half or the second half includes one or more outlet transfer holes defined through a thickness of at least one of the first outlet portion or the second outlet portion.

Abstract: A housing member for a friction clutch and a method for making it. The housing member is made for use with two differently sized fan members. Two annular raised mounting pilot surfaces are provided, one of which is machine finished for mounting one of the two fan members. Two sets of fan member mounting holes are also provided, one set of which is used to mount one of the two fan members thereon.

Abstract: A valve for an engine cylinder includes a head. The valve is selectively moveable between a closed position in which the head blocks a port and an open position in which the head unblocks the port. A lower stem is formed as one-piece with the head, and a thermal cavity formed within the lower stem. The thermal cavity is at least partially filled with a heat transfer medium. An upper stem is attached to the lower stem opposite the head. A thermal barrier is located adjacent a junction of the lower stem and the upper stem.

Abstract: A method of manufacturing a pump assembly includes sand casting a pump housing with a cavity and die casting an impeller that includes pump blades and a first portion of a shroud. The pump housing may be sand cast as a one-piece component and the impeller may be die cast as another one-piece component. A pump cover is provided with a second portion of the shroud. The pump cover is inserted into the cavity so that the second portion of the shroud is adjacent to the first portion of the shroud, providing a substantially continuous surface defining flow channels through the impeller. A pump assembly manufactured according to the method is also provided.

Abstract: A dual drive radiator fan and coolant pump system for a liquid-cooled reciprocating internal combustion engine includes a coolant pump with an impeller shaft driven by a first drive extending between the engine's crankshaft and a pump pulley and hub mounted upon the impeller shaft. A second drive extends between the crankshaft and a fan hub journaled upon the pump hub, so that the coolant pump and fan hub are driven independently.

Abstract: An engine cooling system and method that will allow an engine cooling fan to be driven independently of the engine speed. The engine cooling fan is driven by the engine crankshaft, but includes an electronically controllable fan clutch between the fan and the crankshaft. A control module electronically controls the engagement of the fan clutch based upon engine and vehicle operating conditions. A water pump for pumping coolant through the engine cooling system may also be driven by the crankshaft of the engine, but with an electronically controlled pump clutch between the engine crankshaft and the water pump.
