    摘要: A control for a pressure fluid supply system is described, in particular for the high pressure in a fuel injection system, for example for an internal combustion Diesel engine, by means of which the pressure in a common high-pressure line supplied by a high-pressure pump, i.e. in the common rail, to which individual consumers are connected, is controlled in accordance with the instantaneous pressure fluid requirements. For adapting the pressure in the common high-pressure line to the pressure fluid requirements of the consumers, i.e. the injection nozzles, a device for limiting the amounts of fluids conveyed is associated with the high-pressure pump, which has at least on adjusting element which can be changed by means of an adjusting signal representing the instantaneous pressure fluid supply situation in the common rail. To avoid an elaborate pressure sensor device in the common rail and for the simultaneous improvement of the reaction behavior of the control, in particular when reducing the high pressure in the common rail, the adjusting signal is derived from the amount of fluid throughput in the delivery line of a pressure control valve connected to the common rail. The pre-conveying pressure or the pre-conveying amount available to the high-pressure pump is affected by means of this adjusting signal in the sense of a regulation of the pressure in the common rail.

    摘要: A pump having a number of radial cylinders each housing a sliding piston. Each cylinder is closed by a respective head, and comprises an intake valve and a delivery valve having respective seats inside a plate. The intake valve is located at the end of an intake channel having a first portion through the plate, a second portion formed between the head and the plate and perpendicular to the axis of the cylinder, and a third portion parallel to the cylinder axis. The delivery valve presents a truncated-cone-shaped seal communicating with the pumping chamber via a conduit also extending through the plate; and the two plungers are made of ceramic and guided by a respective retainer.

    摘要: A pump comprising a number of radial cylinders arranged a given angular distance apart about a drive shaft and each housing including a piston resting radially on a respective pad by virtue of the action of a return spring. The connection between the piston and pad comprises a retainer for preventing in-service detachment of the pad, which rests on a respective flat portion of a cam mounted for rotation on an eccentric portion of the shaft. The force on the pad produced by sliding friction between the pad and the flat portion of the cam and directed perpendicular to the axis of the cylinder is absorbed by the piston.

    摘要: An engine brake for a multicylinder internal combustion engine includes valves that can be periodically opened briefly, in each case outside the exhaust stroke. In the vicinity of the applicable valve drive, a hydraulic piston is provided that is triggered synchronously with the engine rpm via an associated control line by a hydraulic pressure distributor fed by a pump. To improve the accuracy of control over the entire engine rpm range, the various valves are assigned a central positive displacement pump that runs synchronously with the camshaft rpm and whose outlet line leads to the hydraulic pressure distributor, which has a distributor disk. In engine braking operation, an alternating connection of the applicable control line to either the pump outlet line or a low-pressure region of the hydraulic control circuit is effected synchronously with the engine rpm by means of the distributor disk.

    摘要: A radial-piston pump has at least one delivery unit with a delivery element. A pump casing is provided which has a first accommodation space for a medium to be delivered and a second accommodation space for a lubricant, the pump casing further has an eccentric side and a casing side. A separating device separates the first accommodation space and the second accommodation space from one another. The separating device has a first sealing element disposed fluid-tightly on the casing side of the pump casing and a second sealing element disposed on the eccentric side and connected fluid-tightly with the first sealing element. A shaft bearing configuration is disposed in the pump casing and supports an input shaft having an end portion. An eccentric element is disposed on the end portion of the input shaft. The second sealing element is disposed so as to be capable of sliding in a circumferential direction of the eccentric element. In this manner, a rotary motion of the input shaft is converted by the eccentric element into a radial motion of the delivery element of the delivery unit.

    摘要: A regulatable coolant pump and a method for regulation of this regulatable coolant pump for internal combustion engines, which is driven by way of a pulley actives a valve slide using an electromagnetically activated piston pump equipped with a return spring in the form of a pressure spring. The pump implements a “pump feed” using many small “partial lifts.” A “leakage volume stream” that flows opposite to the “pumped volume stream” is superimposed on the “pumped volume stream” via the arrangement of circular apertures both in the inlet valve membrane of the working piston and in the outlet valve membrane so that the valve slide can be moved in defined manner and in a very robust and reliable manner, with low drive power via the defined superimposition of these two volume streams.
