Abstract
1,250,522. Fluid-pressure operated motors. TRICO-FOLBERTH Ltd. May 15, 1969 [Feb. 16, 1968], No. 3209/71. Divided out of 1,250,521. Headings F1A, F1M and F1S. A fluid-pressure operated motor has a motor chamber 1 and a motor member 2 movable to and fro by fluid-pressure difference, pilot valve means 25 responsive to the movement of the member to operate a main valve 26 by fluidpressure difference and thereby reverse the member at the end of each stroke and a manually operable control member 37 movable between a first position which causes the motor to operate and a second position which causes the motor member to stop at the end of a stroke in a predetermined direction. A further valve means is controlled by the control member and arranged so that on movement of the control member to the second position then according to the direction of movement of the motor member at that time either the main valve is held in a condition such that the motor member will complete a stroke in the predetermined direction and will then stop or the main valve is moved to that condition at the end of a stroke opposite to the predetermined direction and is thereafter held in that condition. Specification 1, 250, 521 is referred to.
