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 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 relates to a pressure valve (1), especially for a piston pump provided for conveying a pressure medium in slip regulated hydraulic brake systems, whereby the pressure valve (1) comprises a valve seat body (10) and a valve cover body (11). A preloading element (12, 12', 12'') and a valve element (13) are provided in the chamber (19) which is formed between the valve seat body (10) and the valve cover body (11). The aim of the invention is to provide a pressure valve which can be economically produced, can be easily assembled and which is exceptionally reliable. To this end, the valve seat body (10) and/or the valve cover body (11) are produced without cutting.

The invention concerns a closure device for closing ducts which convey pressure medium in a housing (6), said ducts being closed by a closure member (4) which is pressed into a duct and on whose outer periphery at least one moulding (9) is provided. When the closure member (4) is pressed into the duct, basic material of the housing (6) is urged into this moulding (9) to produce a form closure. The duct is in the form of a stepped bore whose outer bore section (1) which is remote from the pressure medium side and has a larger diameter merges via a shoulder into an inner bore section having a smaller diameter and facing the pressure medium side. The closure member (4) has two piston sections which correspond to the two bore sections (1, 8) and have diameters of different sizes. The moulding (9), which is undercut relative to the smaller diameter, is formed between these piston sections and the base material producing the form closure is pressed into the moulding (9) by plastic deformation. On the outer bore section (1) remote from the pressure medium side there is at least one support surface (2) against which a support surface (3) of the closure member (4) directed towards the housing outer side can be applied.

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 hydraulic motorcycle braking system, in which the pump suction valve (25), which is situated in the braking circuit that does not contain the isolating and change-over valves (19, 20), has a higher opening pressure than the pump suction valve (24) which is situated in the braking circuit provided with said isolating and change-over valves (19, 20). As a result of the invention, pressure oscillations initiated during the start-up of the pump cannot have a retroactive effect or only have a slight retroactive effect on the actuated brake master cylinder (13 and 7).

The invention relates to a motor/pump unit, especially for antislip automotive brake systems, comprising a receiving body (3) for hydraulically active components, an internal geared wheel pump with pump components comprising a pinion internal geared wheel combination disposed between two housing parts (20,21), said pump components forming a pre-mounted unit, and a motor (2) for driving the internal geared wheel pump. The aim of the invention is to provide a motor/pump unit which enables the internal geared wheel pump to be integrated into a receiving body in a space-saving and low-cost manner. This is achieved by arranging the housing parts (20,21) in a temporarily adjacent manner by means of at least one security element (38, 46) such that a final orientation of the housing parts (20,21) in relation to each other occurs when the unit is inserted into the receiving body (3).
