Abstract

730,060. Wind-motors. ALLGAIER WERKZEUGBAU GES. Dec. 19, 1952 [Dec. 21, 1951; July 26, 1952], No. 32200/52. Class 110 (3). A wind power plant with variable-pitch vanes embodying means for increasing the starting moment comprises an initially stressed spring which is adapted to swing the vanes, when at rest, through a small angle about their axes and means operatively associated with said spring for additionally stressing the latter, which means is actuated by the running plant. The vanes 2 of a wind motor are displaced when its normal speed is exceeded by a governor 11 acting against the influence of a spring such as a spring 15, Fig. 1. The spring 15 acts on the vanes through a rod 12, a connecting star 13 and push rods 14. A device 17 for holding the vanes in the starting position comprises a spring 18 which is initially stressed to counteract the force of the spring 15. When the wind motor is rotated it drives an oil pump 23 thereby feeding oil to the device 17 and comprising the spring 18 to permit the vanes to move into the operative position. In the embodiment of Fig. 1 the rod 12 is connected to the piston rod 19 of the device 17 by a lever 16 and a hydraulic relay 26 is incorporated in the pump circuit to permit the spring 18 to turn the blades into the starting position at an accelerated speed. A baffle plate 36 controls a discharge valve 35 in the member 17 thereby permitting the spring 18 to adjust the vanes in accordance with the wind velocity. The wind motor drives an electric generator 9 through the gearing shown. In the embodiment of Fig. 4, an oil outlet is disposed in the supply line of the device 17 and is controlled by a member 40 responsive to the speed of the governor 11; the arrangement being such that the port is uncovered when the normal speed of the motor is exceeded to permit the spring 18 to influence the vanes 2 accordingly. The member 17 has one or more ports 41 which limit the stroke of the piston 20 and communicate with the oil sump 42 feeding the wind wheel bearings. An additional control member responsive to a baffle plate is likewise incorporated in the embodiment of Fig. 4; the baffle plate being actuated by wind pressure, by hand or, in so far as the wind motor of Fig. 4 drives a piston water pump, a float.
