Definitions

  • Loaders and like implements having a boom and a bucket operated by hydraulic cylinders require that in a lifting cycle the boom be litfed while the bucket is simultaneously rolled back.
  • a valve body having a pair of spaced parallel bores, a pair of side-by-side high pressure outlet or work passages connecting with each bore and each leading to a motor port at the exterior of the body, exhaust passage means communicable through each of said bores with said high pressure outlet passages, a valve element in each of said bores, movable axially therein from a neutral position to either of at least two operating or work positions to selectively govern communication between said outlet passages and said exhaust passage means, said body having an inlet and an outlet connected by a through passage which transversely intersects said bores and through which pressure fluid supplied to the body inlet flows directly to the body outlet when said valve elements are all in their neutral position, but which through passage is blocked by any of said valve elements when said element is in either of its operating positions, said body having a parallel passage means extending transversely of and communicating with bores and terminating in said body to form a passage closed at one end and communicating with the body inlet at the opposite end, said parallel
  • FIGURE 1 is a horizontal section through a valve assembly according to my invention
  • FIGURE 2 is a section on the line 11-11 of FIGURE and FIGURE 3 is a section on the line IIIIII of FIG- URE 1.
  • valve body 10 having spaced parallel bores 11 and 12.
  • a pair of side-by-side high pressure outlet passages 13 and 14 connect with bore 11 and a like pair of outlet passages 15 and 16 communicate with bore 12.
  • Exhaust passages 17, and 18 intersect the bores 11 and 12 adjacent and on opposite sides of outlet passages 13, 14 and 15, 16.
  • a valve element 19 is axially movable in bore 11 and a valve element 20 is axially movable in bore 12.
  • An inlet 21 connects a through passage formed of a bifurcated passage 22 intersecting bore 11 on opposite sides of a single passage 23 which becomes bifurcated to intersect bore 12 on opposite sides of passage 24.
  • the through passage connects at the inlet 21 with a source of high pressure fluid.
  • a parallel passage 30 extends from one arm of the bifurcated passage 22, parallel to passage 23 to intersect bore 12 adjacent one arm of bifurcated passage 23. Fluid from passage 22 passes through check valve 31 in passage 30 to maintain the passage under pressure. .
  • fluid flow through bore 12 from passage 23 to passage 24 is interrupted and high pressure fluid enters openings 32 in valve element 29 thence through the hollow interior 33 of the valve element 20 and out openings 35 in the wall of the valve element into work passage 15 and from thence to the operated fluid motor not shown. Fluid from the opposite side of the fluid motor is returned through work passage 16, through bore 12 around groove 36 in valve element 29 to exhaust passage 18.
  • valve element 19 When the valve element 26) is in this position, the valve element 19 operates as a priority valve, because its operation to either work position prevents flow to passage 23, thereby preventing flow of fluid to valve element 20.
  • the openings 32 In the second operating or Work position of valve element 20, the openings 32 connect passage 30 through the hollow bore 33 of valve element 20 and through openings 35 with work passage 16. Fluid flowing through this path acts in parallel with the fluid in valve element 19 in all its work positions. Return fluid enters work passage 15 and is carried through bore 12 around groove 37 to exhaust passage 17.
  • the valve element 20 When it is desired to place the valve element 20 in the float position in which fluid from one side of the work motor is delivered directly to the other, the element 20 is moved to its extreme left position viewing FIGURE 1. In this position the groove 36 connects passages 15 and 16 through bore 12' with a minimum of fluid flow loss and makes possible for the first time to virtually eliminate loss of lowering speed in the valve element, which in the past has been the problem area.
  • a valve body having a pair of spaced parallel bores, a pair of side by side high pressure outlet passages connecting with each bore and each leading to a motor port at the exterior of the body, exhaust passage means communicable through each of said bores with said high pressure outlet passages, a hollow valve element in each of said bores movable axially therein from a neutral position to either of at least two operating positions to selectively govern communication between said outlet passages and said exhaust passage means, said body having an inlet and an outlet connected by a through passage which transversely intersects said bores and through which pressure fluid supplied to the body inlet flows directly to the body outlet when said valve elements are all in their neutral position, but which through passage is closed by either of said valve elements when either of said elements is in either of its operating positions, said body having a parallel passage means extending transversely of and communciating with both bores and terminating in said body to form a passage closed at one end and communicating with the body inlet at the opposite end, said parallel passage selectivelyicommuni
