Abstract: A process is disclosed for regulating the capacity of lubricant pumps. The capacity of the pump is regulated by the pressure at the pump outlet or at a consumer site, so that when the pressure increases the pump capacity is effectively reduced. A regulatable lubricant pump, in particular a vane cell pump (1), has a pressure-controlled regulating arrangement (2). In order to obtain a process for controlling lubricant pumps and a corresponding lubricant pump which as a whole consume less energy, the feeding capacity of the pump is additionally limited in an independent manner by detecting the temperature and/or speed of rotation. As for the lubricant pump itself, it is provided with a regulating arrangement (3) having a sensor (4) for the speed of rotation and/or temperature, as well as a regulating member (5), which regulate the effective pump capacity depending on the speed of rotation or temperature, besides the pressure regulating arrangement.

Abstract: The invention relates to a vane pump with a casing (3), a controlling collar (4) sealingly in the casing (3) and mobile transversely to the axial direction of a rotor (1) mounted in the casing (3) and surrounded by said controlling collar (4). An intake region (7, 14) of the pump is defined by a volume, increasing in the direction of rotation of the rotor (1), of a vane cell (5) formed between two neighbouring vanes (2), the rotor (1) and the controlling collar, and a pressure region (8, 11) is defined by a volume of the vane cell (5) decreasing in the direction of rotation. At least one controlling component (22, 23) is provided to set the position of the controlling collar (4) dependently upon the prevailing pumping parameters. In order to provide a vane pump of a space-saving and/or simple and economical design, the invention proposes that at least one recess (20, 21) open towards the outside of the controlling collar (4) be provided on the controlling collar (4) close to the pressure region (8,11) to take a controlling component (22, 23).

Abstract: The present invention relates to a multi-stage regulating valve with a cylinder (1) and an adjusting piston (2) guided inside it to which a regulating pressure can be applied from one side and a return force, e.g. from a pressure spring (3), from the other, in which, depending on the regulating pressure, the piston (2) keeps at least one outlet aperture (41, 42) in the cylinder wall (11) closed or partly or fully opens it and thus closes off a connection to the side of the piston to which the regulating pressure is applied or partly or fully opens it via the outlet aperture (41, 42). To provide a multi-stage regulating valve with the above-mentioned features which can alter the regulating characteristics over a wide range depending on the position of the piston even without the use of several return components, the invention proposes that the piston (2) consist of at least two partial pistons (21, 22) to which the regulating pressure can be applied, where the force of the return component (3) can be applied to a first partial piston (21), whereby a follower (5) interconnects the partial pistons (21, 22) in such a way that a return force is exerted on the second partial piston (22) or other partial pistons via the first partial piston (21) and the follower, the cylinder (1) have at least one stop (6) for the second or other partial pistons (22) limiting the movement of the second or other partial pistons (22, 23) under the effect of the regulating pressure (P) and against the action of the return component (3), while the first partial piston (21) is unaffected by said stop (6) and remains movable against the return component (3) if the regulating pressure (P) increases further.

Abstract: A multi-stage regulator for lubricant pumps with a continously variable feed rate, with a control piston (1) to which can be applied a pressure (P) derived from the output side of the pump (10, 20) and, as the pressure increases, can be moved against the force of a compliant return component (2). To provide a regulator for adjustable lubricant pumps which, with the simplest possible construction, provides a higher-grade regulating characteristic, better meets the actual lubricant pressure and feed rate requirement of the engine and thus operates largely without losses, i.e. without any considerably superfluous hydraulic power, the invention proposes that the control piston (1) consist of a plurality of partial pistons (3, 4) to which pressure can be simultaneously applied and which are movable in parallel and simultaneously over a limited range of displacement, in which there is a stop (9) for at least one of the partial pistons (4) which limits its range of displacement against the direction of force of the return component (2) at increasing pressure, while the other partial piston (3) remains movale further against the force of the return component (2).
