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 motorcycle brake system comprising an accommodating member (11) which is to be produced in the simplest possible manner, is provided with several pressure ducts (5) for the front wheel brake circuit and rear wheel brake circuit (4, 10), and is used for hydraulically connecting two master brake cylinders (7, 13) to the front wheel brake and the rear wheel brake (VA, HA). A couple of wheel brake connections (R1, R2) which can be joined to the rear wheel brake and the front wheel brake (HA, VA) and are disposed between a couple of pressure connections (HZ1, HZ2) that can be joined to the two master brake cylinders (7, 13) extend into the accommodating member (11) on a lateral surface.

The invention relates to a conveyor device for conveying pressure medium into at least one vehicle brake, in a pressure medium container or in a pressure medium accumulator, comprising a pressure medium inlet and a pressure medium outlet, also comprising the following characteristics; a piston (2) is arranged in a displaceable manner in a receiving body (4) and is provided with at least two hydraulically active diameters (D1, D2) for conveyance in the direction of the pressure medium outlet; at least one non-return valve (7, 12; 27) which is used for ventilating a working chamber (11) into which the piston (2) protrudes. The invention is characterised by a multi-part piston (2) which comprises at least two synchronously displaceable partial pistons (13, 14; 13, 24). The first hydraulically active diameter (D1) is associated with the first part piston (13), and the second hydraulically active diameter (D2) is associated with the second part piston (14; 24).

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 hydraulic aggregate for an antiskid-controlled brake system which is provided with noise deadening chambers (6) that are integrated inside a pump boring (3). A hydraulic connection ensues between the brake pressure sensor terminal connections (THZ) and the noise deadening chambers (6) via hydraulic fluid channels (3') which radially or tangentially open into the pump boring (3) and which are connected to the valve receiving holes (2) of the first valve row (X) of an accommodating body (1), said valve row accommodating the inlet valves.

The invention concerns a hydraulic motor-vehicle brake system with anti-locking control and automatic actuation of the brakes to control the drive and/or travel dynamics, with a brake-pressure generator connected hydraulically via pressure-modulation valves (3) to at least one wheel brake and a hydraulic-fluid accumulator, with at least one pump whose aspiration side is connected to the hydraulic-fluid accumulator and whose compression side is connected to a hydraulic path (13) running from the pressure generator to the wheel brake, the path including the pressure-modulation valves (3) and a pressure sensor (1) connected between the brake-pressure generator and the presure-modulation valves (3). The pressure sensor (1) is mounted in a housing (2) which also houses the pressure-modulation valves (3).
