Claim 0:
1. A foot brake valve (2′) of a pneumatic brake system in a motor vehicle, the foot brake valve comprising:
an installation plate (4′, 4″), on which a brake pedal (14) is pivotably mounted and to which a housing (18′, 18″; 28) of a control unit (16, 26) is fastened,
a spring-loaded plunger piston (36) in an actuating contact with the brake pedal (14) and guided axially movably in a first annular collar (50, 72), which projects upward out of the installation plate (4′, 4″),
wherein the housing (18′, 18″) of the control unit (16) arranged directly beneath the installation plate (4′, 4″) has an intermediate flange (48, 70) which is screw-connected to the main part of the housing (18′, 18″) and which has the first annular collar (50, 72), and wherein the intermediate flange (48, 70) is, with the first annular collar (50, 72), guided in a passage opening (40, 40′) of the installation plate (4′, 4″) coaxially rotatably about a vertical central axis (32), and is connectable in a non-positively locking fashion to the installation plate (4′, 4″) via a releasable clamping connection (62, 76, 77);
wherein the clamping connection (62) is formed by an outer annular groove (52) with a radially inward groove bottom and an upper side wall in the first annular collar (50) of the intermediate flange (48) and by two clamping plates (64, 64′) arranged at the first annular collar (50) diagonally opposite from each other on the installation plate (4′) and engaging the annular groove (52),
wherein each of the clamping plates (64, 64′) is screw-connected to the installation plate (4′) and is angled upward in cross section in a radially inward direction with an axially elevated inner edge (68) and a circular-arc-shaped inner end wall (66), wherein, in an installed state, the circular-arc-shaped inner end wall of each of the clamping plates (64, 64′) bears (66) against the groove bottom (54) of the annular groove (52) and the axially elevated inner edge (68) bears against the upper side wall (56) of the annular groove (52).
