The invention relates to a unit (1), in particular an electrohydraulic unit, with at least two hydraulic connections (2, 3) fastened to it, in particular pipe or hose connections which are provided largely parallel to each other at a defined distance A. The object is to form the system described in such a way that increased miniaturization of the unit (1) is made possible, without having to abandon the automated assembly of the hydraulic connections (2, 3). According to the invention, it is proposed that a screw fitting (5, 6) which can be turned in relation to a pipe (13) or hose is provided for the fastening of the hydraulic connections (2, 3), having a spanner flats portion (7, 8) and comprising an external thread (14), which is received within an assigned receiving bore (9, 10) in an internal thread (15) of the receiving body (11) in such a way that a sealing face (16) sits on a mating sealing face (17) of the receiving body (11), wherein the screw fitting (5, 6) has in addition to the spanner flats portion (7, 8) a further spanner flats portion (12), and that the spanner flats portions (12) have different widths across flats SW.

The invention relates to a hydraulic fluid accumulator comprising a housing (1), whose interior is subdivided into three chambers (2, 3, 4), whereby the first chamber (2) is filled with a gas and separated from the second chamber (3) by a first media separation element (6). Said second chamber is filled with a liquid and is separated from the third chamber (4), which is also filled with a liquid and is connected to a hydraulic line (5), by a second media separation element (7). To guarantee an effective separation of the media within the hydraulic fluid accumulator and thus a significant increase in its functional safety, the invention is characterized in that the second media separation element (7) is embodied by a metal piston (8, 80) which delimits a space that can be deaerated (9, 90) in the housing (1).

The invention relates to a hydraulic unit for slip-controlled braking systems having a plurality of receiving holes (23-28) for transport devices (15a, 15b, 15c; 16a, 16b, 16c) associated with a plurality of hydraulic circuits bundled into groups, wherein the receiving holes (23-28) are disposed at a distance from each in parallel with the upper side (22), and a drive shaft having eccentrics located at the plane spacing for driving the transport devices (15a, 15b, 15c; 16a, 16b, 16c). In order to provide a compromise optimized for manufacturing a small, convenient hydraulic unit, it is proposed according to the invention that three theoretical planes (E1, E2, E3) are arranged in parallel to the upper side (22), each receiving two V-shaped receiving holes for transport devices (23-28) disposed at an angle to each other, and that the drive shaft comprises three separate eccentrics for driving said transport devices (15a, 15b, 15c; 16a, 16b, 16c).

The invention relates to a hydraulic unit of which the receiving body (6) is equipped with a plurality of valve reception bores (1, 2, 3, 10). To reduce the dimensions of the receiving body, the valve reception bore (3) provided for the reception of the electric switching valve is arranged on the plane of the pump bore (4).

The invention relates to a trailer device for driving stabilization of vehicle combinations. In order to design a device for driving stabilization of passenger vehicle trailers in a cost-effective and simple manner, a brake system for braking the trailer by means of an overrun brake (80) and for stability regulation is designed so as to have separating valves (14), switching valves (28), inlet and outlet valves (16, 22) and a pressure build-up pump (25). According to the invention, a stabilizing coupling (38) is also connected by means of a second pressure medium pump (48) to actuators (36a, 36b) which can vary the clamping force of the stabilizing coupling between the trailer and tractor vehicle if the second pressure medium pump (48) conveys pressure medium from the storage tank (27) into or out of the actuators (36a, 36b).

The invention relates to a piston pump, in particular for controllable braking systems such as ABS or ESP. The pump is characterized in that a working chamber (40) of said pump is delimited upstream of a piston (3, 52) by a pressure valve. One end of a return spring (4, 51) is supported against a valve seat support (9, 54) of the pressure valve and the other end restores the piston (3, 52) to its lower dead-centre point. Pumps which are to be mass produced should be as inexpensive and easy to assemble as possible. To achieve this, according to the invention, the return spring (4, 51) can also be fixed directly or indirectly to the valve seat support (9, 54).

The invention relates to a pump or compressor unit of the displacement type, comprising an electric motor (2) with a drive shaft (4), which is rotatably mounted and engages with a housing (8). A gear (6) comprising at least two eccentric elements (18, 19) that can rotate in relation to one another is also provided, said gear converting a rotational displacement into a translational displacement. An elastic element (24), designed to provide a tension, is fixed between the eccentric elements (18, 19) in order to modify the effective cumulative energy value (eS) of the eccentric elements, the latter (18, 19) being integrated into one another, with a radial outer eccentric segment (19) surrounding and engaging with a radial inner eccentric element (18). The quasi-linear relationship between the motor torque and the motor speed, which is predetermined by the construction, is overridden with the aid of a continuously variable gear mechanism. The cumulative energy value (eS) of the eccentric elements on the driven side is varied in accordance with the braking torque. This enables a particularly cost-effective, compact unit comprising a cost-effective electric motor (2) to be produced. As the energy stored in the elastic elements (24) can be made available for other crank angles of rotation α, said energy is also temporarily stored and fed back into the system.

The invention relates to a piston pump (1), especially for delivering fluid under pressure in hydraulic, anti-slip brake system, with at least one piston (5), a suction valve (10) and a pressure valve (11). The suction valve (10) and the pressure valve (11) are embodied in an independently actuated constructive element (7) enabling external testing of the suction and pressure valves (10; 11). Preferably, the constructive element (7) has a sleeve-like segment (8) in which the piston is guided (5).
