Abstract (en)
[origin: WO9951897A1] A low pressure pneumatic valve control system having at least one manually actuable pilot valve (1, 2) to control a respective remote slave valve (3, 4). The system is particularly intended for use with pneumatic patient support apparatus. Both the pilot and slave valves are formed from stiff inelastic mounting (10) with a port (13) formed therethrough. A flexible resilient actuator (11) is mounted on one side of the mounting. A flexible resilient valve member (12) is mounted on the other side of the mounting, to sealingly engage the mounting around the port. The actuator (11) is operative to move the valve member, via the port, out of sealing engagement to permit air to flow through the port.
