Title:
INTEGRATED FOOT CONTROL VALVE ACTUATOR
Document Type and Number:
WIPO Patent Application WO2002058979
Kind Code:
A3
Abstract:
A pneumatic actuator (50) is integrated into a foot control valve(20). It includes a pneumatically activated piston that applies a force to the foot control valve primary piston (32) which, in turn, applies the vehicle brake system. The piston is configured to allow the pedal or treadle actuated plunger (54) to push through the pneumatic actuator and apply the brake system. This finds particular use as an add-on feature for pre-trip inspection systems, as a working brake system, etc.
