Abstract: 794,444. Fluid-pressure servomotor control systems. BENDIX AVIATION CORPORATION. Aug. 22, 1955 [Oct. 18, 1954], No. 24150/55. Class 135. [Also in Group XXXI] A pilot-type valve 10, e.g. for tractor hydraulic lift systems, comprises a motor passage 15 or 16, a pressure supply passage 11 and return passage 14 controlled by a pressureoperated piston valve 31 moved through a neutral position, to which it is urged by e.g. spring means 32, 33, to either of two end positions when an operator actuated pilot valve 51 selectively connects either end of the piston 31 to the pressure passage and as shown the other end to the return passage 53, and an adjustable assembly 37, 112, 114 associated with valve 31 to limit its travel and thereby restrict flow through the passages. The control lands of the pilot valve 51 are slightly longer than the control ports positioned between the pressure chamber 50 and the end return chambers 53, and are formed of the main cylindrical portions 51a, 51b sealing with the pilot valve cylinder and end cylindrical portion 70 on the return chamber side of slightly reduced diameter giving negative lap when the valve is in neutral position. The piston valve 31 has lands defining a first recess 31f or 31g communicating a cylinder motor port with a cylinder pressure port only in one end position of the piston valve, a second recess 31d communicating only with the pressure port in neutral positions and with the motor port in the other end position, and a third recess 30c communicating with the cylinder return port in all positions. A passage 31a in the piston valve 31 connects the second and third recesses and a pressure reducing valve 62 in the return flow path produces a predetermined minimum pressure drop between the pressure and return passages. To regulate the speeds of extension of the motor piston 18b the rate and amount of displacement of the piston valve 31 to the right is adjusted by compressing the spring 33 by the screwed plunger 110. In the neutral position of the piston valve the motor port 15 is connected with the pressure port through a lightly loaded non- return valve 60. The manual lever 21, pilot valve 51 and motor piston 17a are linked by a follow-up lever 23.
