    Abstract: The pump device includes a housing defining insertion holes for a rotation shaft, inlets and outlets, and an internal passage; a first pump element; and a second pump element. The internal passage includes first suction passages communicating from the inlet to a first suction port facing the first end surface of the first pump element directed to one end side; first discharge passages communicating from a first discharge port facing the first end surface to the outlet; second suction passages passing around the first pump element to communicate from the inlet to a second suction port facing the second end surface of the second pump element; and second discharge passages passing around the first pump element to communicate from a second discharge port facing the second end surface to the outlet.

    Abstract: A pump for applying fluid to an assembly, the pump including: a pump housing featuring a circumferential wall surrounding a delivery chamber of the pump, an end-facing housing wall including an outer end-facing surface of the housing which faces axially away from the delivery chamber, an inlet and an outlet for the fluid which emerges on the outer end-facing surface of the housing; a delivery member, moveable within the delivery chamber, for delivering the fluid from a low-pressure side of the pump which includes the inlet to a high-pressure side of the pump which includes the outlet; and an axial gasket which fully surrounds the outlet, in order to separate it from the low-pressure side, in an axial view onto the end-facing wall of the housing. The axial gasket is a spring gasket in the form of a disc spring or hollow-profile spring or V-profile spring or bellows spring.

    Abstract: A stator for a helical gear device includes a first section having first helically convoluted chamber with a set of radially inwardly extending lobes and a second section adjacent to the first section. The second section includes a stack of cutter disks. Each cutter disk includes a front surface, a rear surface, an interior surface defining a central opening extending from the front surface to the rear surface, a forward cutting edge, and a rearward cutting edge. The interior surface forms a same number of lobes for the central opening as the set of radially inwardly extending lobes in the first section. Each cutter disk is aligned along a common centerline, and each cutter disk is rotated slightly relative to each other to form a second helically convoluted chamber with a same pitch as the first helically convoluted chamber. The second helically convoluted chamber exposes, to materials passing through, portions of the forward cutting edge or the rearward cutting edge of each cutter disk.

    Abstract: A tool and a method of using the tool are provided for forming an engine component. The engine has a block defining a first cylinder and a second cylinder spaced apart by a bore bridge. The bore bridge defines a first cooling passage spaced apart from a deck face and extending transversely, and a second cooling passage positioned between the first passage and the deck face and extending transversely. The first and second passages are formed by a casting skin. In forming the engine component, a die is provided that defines a locator recess and at least one core. An insert is positioned into the recess on the die. The insert has a cast shell surrounding a lost core. The component is die cast with the die and the insert to form a cooling jacket. The insert is adapted to form the cooling passages for the bore bridge.

    Abstract: A piston for an internal combustion engine is provided. The piston includes a piston body which is made of steel. The piston body has a crown portion with an upper combustion surface, a pair of skirts which depend from the crown surface, a pair of pin bosses for receiving a wrist pin and a plurality of pin boss bridges which extend from the pin bosses to the skirts. Each of the pin boss bridges extends axially to a lower end which is opposite of the crown portion and has a rib with an increased thickness at its lower end. At least one of the pin boss bridges has a generally flat counter-bore surface for providing a reference location for machining of the piston body.

    Abstract: A piston capable of reducing the frictional resistance between skirt portion and a cylinder inner surface and improving fuel efficiency is provided. The invention is a piston for an internal combustion engine wherein when the piston slides along a cylinder inner surface, a high surface pressure portion occurs at a center of each skirt portion and low surface pressure portions occur at both sides of the high surface pressure portion. The high surface pressure portion of plural portions is provided with a horizontal groove. The low surface pressure portions of the plural portions are provided with an inclined groove that is inclined downward toward the high surface pressure portion and that is connected to an end portion of the horizontal groove.
