Abstract
Official abstract text for this publication.
A vehicle brake circuit including a brake actuator, a manually operable valve, an electrically operable valve and a fluid reservoir for the supply of fluid to the actuator. The manually operated valve may be connected to the fluid reservoir either directly or indirectly through the electrically operable valve, when its position blocks a direct fluid connection with the fluid reservoir. The electrically operated valve controls activation or deactivation of the actuator except when the mechanically operated valve is in an unblocked position and overrides the electrically operated valves control of the actuator.
First claim
Opening claim text (preview).
1 . A vehicle brake circuit comprising a brake actuator, a first manually operable valve, a second electrically operable valve and a fluid reservoir for the supply of fluid to the actuator, said first valve connectable to the fluid reservoir both directly and via the second valve, said first valve biased in a position such that a direct fluid connection between the fluid reservoir and the first valve is blocked and a fluid connection between the fluid reservoir and the first valve is via the second valve and wherein movement of the second valve controls activation or deactivation of the actuator and wherein movement of the first valve out of the biased position overrides control of the actuator by the second valve. 2 . The vehicle brake circuit as claimed in claim 1 wherein the actuator is connected to the fluid reservoir via the first valve. 3 . The vehicle brake circuit as claimed in claim 1 wherein the actuator is connected to the fluid reservoir via a relay valve, said relay valve connected to the first valve. 4 . The vehicle brake circuit as claimed in claim 1 wherein the movement of the second valve is controlled by a control unit. 5 . The vehicle brake circuit as claimed in claim 4 wherein the control unit detects different vehicle conditions and positions of the first and second valves. 6 . The vehicle brake circuit as claimed in claim 1 wherein the movement of the first valve is controlled by a handbrake lever. 7 . The vehicle brake circuit as claimed in claim 1 wherein the brake circuit is a parking brake circuit. 8 . The vehicle brake circuit as claimed in claim 1 wherein the circuit is a pneumatic circuit.
