Abstract
The present invention relates to a hydraulic unit for slip-controlled brake systems, the accumulator accommodating bore (1) thereof opening into the accommodating member (4) between the valve accommodating bores (2, 2′) of the two valve rows (X, Y).
Claims13
Hydraulic unit for slip-controlled brake systems,
- including an accommodating member accommodating inlet and outlet valves in several valve accommodating bores of a first and second valve row,
- including a pump bore that is arranged in the accommodating member outside the two valve rows,
- including a motor arranged coaxially to the pump bore outside the two valve rows and directed into the accommodating member,
- including an accumulator accommodating bore that opens into the accommodating member,
- including several pressure fluid channels connecting the valve, pump and accumulator accommodating bores and being adapted to establish a hydraulic connection between several brake pressure generator connections and several wheel brake connections,
- characterized in that the accumulator accommodating bore (1) opens into the accommodating member (4) between the valve accommodating bores (2, 2′) of the two valve rows (X, Y).
3 more elements
Hydraulic unit as claimed in any one of the preceding claims,
- characterized in that on either side of the pump accommodating bore (5), brake pressure channels (13) extend from the valve accommodating bores (2) of the second valve row (Y) to the wheel brake connections (VR, HL), said channels (13) being provided as blind-end bores in the wheel brake connections (VR, VL or HR, HL).
Hydraulic unit as claimed in any one of the preceding claims,
- characterized in that the valve accommodating bores (2) of the second valve row (Y) are penetrated by a collecting channel (15) that extends in parallel to the second valve row (Y) and leads to a supply reservoir connection (16) arranged on the second housing end face (12).
Hydraulic unit as claimed in any one of the preceding claims,
- characterized in that a pump cartridge which accommodates a geared pump or vane-type pump is inserted into the pump accommodating bore (5).
