摘要： The invention relates to a method for producing a sliding surface on a machine element, in particular a cam follower, wherein the machine element is first provided with a coating on at least part of the surface of the machine element, into which coating a surface structure is then introduced by laser structuring. In order to be able to introduce a surface structure that does not penetrate the coating even in the case of low layer thicknesses (s1) of the coating, the introduction of the surface structure is performed by laser interference structuring.

摘要： A fuel injection pump includes a cam rotating with a camshaft, a tappet reciprocating in response to rotation of the cam, a cylinder, a plunger, and a thrust washer. The thrust washer is located between the cam and a casing housing the camshaft at both ends of the cam in an axial direction of the cam. The tappet includes a tappet body, a roller, a supporting member, and a contact surface formed at an outer peripheral part of the tappet. The thrust washer includes a rotation restricting part that protrudes toward the tappet over a maximum lift position. The rotation restricting part restricts rotation of the tappet relative to a center axis of the tappet body by being contact with the contact surface.

摘要： A columnar hydraulic tappet comprises a housing, in which a plunger is correspondingly mounted. A high-pressure chamber extends between a lower end surface of the plunger and a lower side of the housing. An outer ring groove is disposed on the outer diameter of the housing, an inner ring groove is disposed in the radial inner side of the housing, and housing oil feed holes are disposed between the inner ring groove and the outer ring groove. The lower end inside the housing is provided with a grinding wheel groove, an upper end wall of the inner ring groove of the housing is a first internal cylindrical wall, and a housing inner-wall between the lower end of the inner ring groove of the housing and the grinding wheel groove is a second internal cylindrical wall.

摘要： A roller for a mechanical fuel pump assembly includes an elongate body extending from a first axial end to a second axial end of the elongate body over an overall length of the elongate body. The elongate body defines an effective length that is less than the overall length. The elongate body defines a uniform circular cross section over a second length of the elongate body. The second length is 75 to 90 percent of the effective length and the second length extends between a first plane and a second plane. A first area of reduced cross section extends axially outward from the first plane to a third plane located axially inward of the first axial end; and a second area of reduced cross section extends axially outward from the second plane to a fourth plane located axially inward of the second axial end.

摘要： A method of controlling an operation of an inlet valve system arranged in connection with each cylinder of an internal combustion piston engine, includes monitoring at least one parameter relating to engine load conditions, controlling using a primary control procedure an opening and closing timing of an inlet valve in response to the at least one parameter, and feeding charge air into the cylinder when the inlet valve is open. In a secondary control procedure a parameter relating to engine load conditions is measured and the closing timing of the inlet valve of the inlet valve system is controlled in response to the at least parameter independently from and with higher priority than the primary control procedure.

摘要： The invention proposes a subassembly of a hydraulic variable valve train of an internal combustion engine, having a guide bushing (4) that can be installed in a hydraulic housing (3), and having a piston (5) supported therein so as to be axially movable for actuating a gas exchange valve (1), and having a valve element (7) that, together with the end face (10) of the piston distant from the gas exchange valve, defines a hydraulic pressure chamber (11) in the guide bushing, wherein the valve element is a throttle check valve that allows hydraulic medium to flow out of the pressure chamber throttled by a continuously open throttle opening (16) and allows hydraulic medium to flow into the pressure chamber with little throttling by a ball check valve (17). The subassembly is intended to be implemented as a modular unit assembled outside of the hydraulic housing, wherein the guide bushing and the valve element are fastened to one another, and the piston is secured in a captive manner in the guide bushing.
