Abstract: A blow-off metering valve for a hydraulic control unit assembly of a brake system including a valve seat. The valve seat includes a wall that extends about an axis between a first end and a second end. The wall defines a passage that extends axially between the first and second ends for transmitting a fluid through the valve seat. An annular flange extends axially from the second end of the wall toward the first end of the wall and tapers radially inwardly. A blocking member is axially movable toward and away from the annular flange for selectively creating a seal at the passage. A biasing element biases the blocking member toward the annular flange. The annular flange terminates at a distal end that is radially spaced from the wall. The annular flange defines at least one flow channel that extends axially for allowing fluid to bypass the blocking member.

Abstract: A pressure supply unit for a brake system including a booster body that defines an axially extending cylinder. A piston is slideable within the cylinder. The piston defines a bore that receives a spindle. The spindle is rotationally fixed and axially moveable for providing the axial movement of the piston. A motor is positioned about the spindle and is configured to axially translate the spindle and piston. A ball and socket joint connects the piston and spindle while accommodating pivoting movement of the spindle. The ball and socket joint includes a ball at a front end of the spindle and a socket in the bore of the piston which receives the ball.
