Abstract
1,182,690. Hydrostatic transmissions. APPLIED POWER INDUSTRIES Inc. 29 Aug., 1967, No. 39464/67. Heading F2D. [Also in Divisions E1 and G3] The engine 20 of an asphalt laying vehicle drives a variable-output pump 24 supplying a motor 28 driving an asphalt distributer 38. A pump 54 driven by the motor 28, through variable-speed gear-box 44, supplies line 66 and the latter is connected to the input of pump 86 driven at a speed proportional to the speed of the vehicle by wheel 70. If the vehicle speed increases, pump 86 lowers the pressure in line 68 and piston 40 increases the pump output, and thus the distributer speed, until the output of pump 54 matches the increased output of pump 86. Set point control is effected with gear-box control lever 48.
