ABSTRACT:
A relay valve arrangement useful in an ABS system comprises a relay valve, a source of control pressure, a control pressure circuit, a control chamber which receives the control pressure from the control pressure circuit and thereby determines the configuration of the relay valve, a control valve through which the control pressure is delivered to the control chamber, and a return valve connecting the control chamber to the control pressure circuit so as to by-pass the control valve to deaerate the control chamber when the control pressure in the control chamber is greater than the control pressure in the control pressure circuit. The control valve includes a solenoid-actuated inlet valve having an armature, and a solenoid-actuated outlet valve. The return valve is designed so that at least part of it constitutes an armature support for the armature of the solenoid-actuated inlet valve and is coaxial with this armature.
