Abstract: A cuboidal housing block, particularly for a hydraulic modulator to generate, control or regulate a hydraulic pressure in a brake circuit of an electronically controllable power-brake system. Housing blocks have, inter alia, a mounting side which is provided for mounting an electronic control unit. To save on weight and material, a recess is provided on one long side of the housing block, the recess being in the form of a groove that is closed on the sides and otherwise open toward the surroundings of the housing block. The recess is bounded lengthwise by bars, an outer flank of these bars transitioning seamlessly into the mounting side and enlarging its area.

Abstract: A pump assembly for generating pressure in a brake circuit of a controllable power brake system of a motor vehicle. The pump assembly has, as a pressure generator, a piston-cylinder unit in which a piston is actuated with the aid of a piston drive. The piston drive converts a rotational movement, with which a nut of this piston drive is driven, into a translatory movement of a spindle, which is in turn connected to the piston in a rotationally fixed manner. The piston is a steel component in which a plastic deformation at a piston head forms a device for connecting the spindle to the piston in a rotationally fixed manner.

Abstract: A brake actuating device of a vehicle brake system has a pump housing which has a housing opening surrounded by a wall. The housing opening includes a housing axis along which a piston is to be accommodated in the housing opening in an axially displaceable manner.

The brake actuating device further has a projection projecting from the wall into the housing opening. The projection is provided axially next to the guide region in the housing opening. The guide element is placed axially on the projection.
