Abstract
547,955. Hydraulic machines; fluid-pressure servomotor-control systems. AUTOMOTIVE PRODUCTS CO., Ltd., CLENCH, E. C. S., and CARLTON, Q. H. March 17, 1941, Nos. 3650/41 and 1712/42. [Classes 69 (ii) and 135] [Also in Group XXII] A profile duplicating machine, in which the work piece 23 and the pattern or model 24 are mounted so as to be moved in unison relatively to a milling tool 21 and a follower 25 by means of a double-acting hydraulic motor 13 having a pair of working spaces 94, 96 supplied with pressure fluid from a pump 85 through the medium of a valve 28 operated by the follower 25, is constructed with a relay valve 51 which is responsive to pressure changes in one of the working spaces 94, 96 and is actuated thereby so as to cause a change in the pressure of the other working space in the opposite sense to the change in the first space.
