Abstract

A remotely controlled piston (12) and cylinder (10) is used to open a garage door. The cylinder (10) is fixed to a foundation and the piston rod connected by pulleys to the door. The pressure in a direct mains water supply drives the piston (12) into the cylinder (10) when it is in the closed position to open the door. The supply of water to the cylinder is controlled by a solenoid valve (54) in the supply conduit (32), the valve being opened on receipt of an opening signal from a transmitter and closed when the piston is in the open position by a reed limit switch (40) operated by a magnet (38 not shown) carried on the piston (12). On receipt of a closing signal, a solenoid valve (58) in a bleed conduit (60) opens and the water is led to waste, travel of the piston (12) to closure being again controlled by a second reed switch (41) closing the solenoid valve (58) in the bleed conduit (60). <IMAGE>
