Zusammenfassung:	1312004 Hydrostatic transmission control ROBERT BOSCH GmbH 23 April 1970 [24 April 1969] 19411/70 Heading F2D [Also in Division F1] In a vehicle hydrostatic transmission control in which a lever 6 controlling a pressure-relief valve 11 in a line 10 e.g. from a feed pump 8 or an accumulator, sets the desired vehicle speed, the control of the engine fuel supply and the displacement of the transmission pump are controlled at optimum efficiency by hydraulic pistons 22, 17 in accordance with the pressuie P H1 and P H2 in lines 13, 131 between respective fixed, 14, 141, and variable, 24, 19, throttles, the variable throttles being adjusted by the transmission high pressure p in a line 35 acting to move a spool 25 in opposite directions to maintain the product of the pressures P H1 and P H2 , and hence the vehicle speed, constant. The spool 25 may be replaced by an eccentrically mounted non-circular disc (36), Fig. 3 (not shown), turned by the pressure p to selectively uncover the throttles 24, 19. The transmission pump may be of the axial piston type. The motor may be non-variable or variable by the pressure P H in a line 12.
