Abstract
1295154 Valves EATON CORP 22 June 1970 [8 July 1969] 30169/70 Heading F2V A flow-controlling arrangement, which is designed to operate a motor 35 and to prevent outflow from such motor in the event of the supply pump 9 failing, comprises a spool valve member 12 which is biased by a spring arrangement 43-49 to the shown neutral position in which it isolates the motor, and a pressureregulating valve member 14 which is biased by a spring 6 to the position shown wherein the spool member is isolated from the pump. Upon actuating the pump, valve member 14 is forced by the pumped fluid against its spring such that communication is established between the pump 9 and the spool fluid-supplying passage 17, the passage 17 branching into two parts 18 and 19. Upon moving the spool to the right, as seen in the drawing, the motor piston end is supplied with pressurized fluid from passage 18 and through spool grooves 38a, 37a and passage 34a, whilst the motor rod end is exhausted via passage 34, spool grooves 38, 37 and passage 36. Simultaneously a spool transverse passage 42a communicates with passage 34a and so the spool-interior bore 39a is pressurized with the result that a ball valve member 50 is seated against a similar second spool passage 39; in consequence, a balancing chamber 24 behind valve 14 is also pressurized. Accordingly, and for a given setting of the spool 12, fluctuations in the inlet supply act upon opposed sides of member 14 and so position member 14 such that the supply to passage 17 is maintained constant. In the event of the pump 9 failing, valve member 14 is automatically moved by spring 6 to the position shown wherein reverse flow in passage 17 is prevented. Fig. 2 (not shown) depicts a modified, manually-operable spool valve wherein the passages which lead to the balancing chamber 24 are formed entirely in the body of the valve arrangement.
