Abstract: An inlet or outlet valve for a pump comprises a closing body (3) pretensioned by a spring element (4). The closing body (3) can open or close a passage on a valve seat (2). The valve also comprises a guide element (5) for guiding the closing body (3). Inside the guide element (5), the closing body (3) is guided at least on a first guiding area (9) and a second guiding area (10).

Abstract: A screwed connection has at least one first component (1) which is provided with an internal screw thread (2) and which is screwed together with a second component (3) which is provided with a matching external screw thread (4). The screwed connection is used to transmit a tightening power (F). Thread sealants (6) are introduced between the external and the internal screw thread, thereby sealing the screwed connection.

Abstract: 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.

Abstract: A device presenting a high-pressure pump, and a low-pressure pump connected pstream from the first. To prevent damage in the event of a fault on the device, the connection between the low- and high-pressure pumps is provided with a cutoff valve which is closed in the event of a fault on the low-pressure pump to prevent the intake of solid particles by the high-pressure pump. Also, in the event of a fault on one of the injectors, detected on the basis of the operating conditions of the engine, the low-pressure pump is disconnected to prevent seriously damaging the engine.

Abstract: 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.

Abstract: 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.

Abstract: A pumping apparatus is disclosed comprising a tank containing a fluid to be umped, a main pumping stage for pumping a controlled amount of said fluid at a predetermined pressure, a supply pump for supplying fluid from said tank to said main pumping stage in excess to said controlled amount, and feedback means for feeding the excess fluid back to said tank along a given drain path; wherein the improvement includes at least part of said drain path running in regions of said main pumping stage subjected to severe thermal and/or mechanical stress.
