PCT No. PCT/DE96/00952 Sec. 371 Date Feb. 6, 1997 Sec. 102(e) Date Feb. 6, 1997 PCT Filed Mar. 5, 1996 PCT Pub. No. WO97/01050 PCT Pub. Date Jan. 9, 1997The electro-hydraulic control device is designed to control a continuously variable loop transmission including a hydraulic bevel disk displacement device having two pairs of bevel disks, each pair of which has piston/cylinder elements with a piston chamber, and a pump for supplying one of the piston chambers with hydraulic oil. The electro-hydraulic control device supplies and regulates a hydraulic pressure in the piston chamber by means of a flow control valve (50) and a proportioning pressure relief valve (30). The electro-hydraulic control device also includes a pressure sensor (90) for generating an electronic pressure sensor signal according to the hydraulic pressure in a low-pressure control pressure line (34) connecting the flow control valve (50) and the proportioning pressure relief valve (30) and an electronic control unit for generating an electrical current for actuating the flow control valve (50) according to the pressure sensor signal. The electronic control unit includes a multiplier (95) connected between the flow control valve (50) and the pressure sensor (90) for generating the electrical current from the comparatively reduced pressure sensor signal from the sensor connected with the control pressure line. |
