Abstract
A hydraulic unit for a slip-controlled brake system includes noise damping chambers (6), and at least one element which defines a direction of inflow and outflow of the pressure fluid for the throughflow and deviation of the pressure fluid in the noise damping chamber (6). In one embodiment, this is accomplished by two inclined channels (10, 11). An inclined channel (10) extends from a lateral surface of the accommodating member (1) through the wall of the pump bore (3), said inclined channel (10) opening at an acute angle in the area of the bottom of the noise damping chamber (6). Likewise, an additional inclined channel (11) extends from the lateral surface of the accommodating member (1) at an acute angle through the wall of the noise damping chamber 6, said inclined channel (11) opening in the bottom area of a valve accommodating bore (2) in the first valve row X.
