Abstract

1,239,841. Hydraulic motor control circuits. DR-ING H.C.F. PORSCHE K.G, Oct.17, 1969 [Oct.17, 1968], No.51038/69. Heading F1P. Cooling of hydraulic fluid prior to it being forced by a pump 7 Fig.1 through a line 9 to actuators 10 -- 10"' suitable for closing hatches 12 on an amphibious vehicle is effected by forcing the fluid by a pump 1 past an open temperatureresponsive valve 16 and through a line 22, a radiator 3 cooled by a fan driven by an hydraulic motor 2 in the line 22 and back to the reservoir 5 through lines 23, 24, 38 Fig.2, 34, 35; the valve 17 being normally in abutment with a setting piston 30 in conduit connection with line 9 whereby when line 9 is pressurized piston 30 moves to the right and the valve 17 is moved by a spring 29 to the closed position. In operation and assuming no pressure in line 9 and the fluid to be at the desired low temperature, the delivery line 33 is connected through a port 28 in a sleeve 18 and through a bore 38 in valve body 20 to the return line 34. A temperature rise causes valve 17 to expand against a spring 29 and so displace the: sleeve 18 to a position in which port 28 registers with a body groove 36 whereby pump delivery is connected to the motor 2 and radiator 3.
