ABSTRACT:
Dual-circuit pressure regulators for brake systems are known in which the two valve pistons are acted upon by means of two separate control springs. In this known arrangement, it is difficult to make the forces of the two control springs equal and the forces of the two control springs are not adjustable. To overcome these disadvantages, the dual-circuit pressure regulator of the present invention employs a single control spring common to the two valve pistons and one valve-closing member interacts with an auxiliary housing which is shiftable relative to a main housing and can be locked in a selected position in the main housing. The force of the control spring is determined by the position of the auxiliary housing in the main housing.
