Abstract

495,935. Valves; control of motors. HURST, W. F. F. MARTIN-, and BRITISH THERMOSTAT CO., Ltd. March 10, 1938, No. 7523. [Class 135] [Also in Group XXXVII] A plate 3 is pivoted to an actuating member 4 traversed across a fluid passage by a screw 5 and is guided by slots 14 so that it may lie parallel with the fluid passage. The fluid passage and plate are preferably square. An electric motor 9 may actuate the screw, its motion being limited by switches 20, 21 actuated by a spindle 18 passing through the screw 5 and carrying two stops 16 which the member 4 abuts.
