Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As it is shown in figure 1, be the structural representation of driven valve valve body embodiment of the present invention. The driven valve valve body of the present embodiment, including valve body body 1, spool chamber 24 it is provided with in valve body body 1, on the inwall of spool chamber 24, annular is laid with four oilholes, it is additionally provided with the axis installing hole 10 vertical with spool chamber 24 axis and the axis pin-and-hole 16 parallel with spool chamber 24 in valve body body 1, in valve body body 1, is additionally provided with the pendulum cotter way 19 communicated with pin-and-hole 16 and spool chamber 24.
As it is shown in figure 5, the structural representation of the driven valve for adopting the present embodiment driven valve valve body. This driven valve, including valve body 1, is provided with spool chamber in valve body 1, be provided with inner spool 2 and outer spool 3 in spool chamber, and outer spool 3 is sleeved on inner spool 2. The dead in line of four oilholes respectively a fuel feed hole 4a, a spill port 4b and two the oil outlet 4c arranged on spool chamber inwall, the axis of fuel feed hole 4a and spill port 4b, two oil outlet 4c's is axially coincident and vertical with the axis of fuel feed hole 4a. Outer spool 3 is correspondingly provided with oil-feed through hole 5a and spill port 4b respectively with fuel feed hole 4a be correspondingly provided with oil return through-hole 5b and be correspondingly provided with out oil hole 5c with oil outlet 4c, the periphery wall of inner spool 2 is provided with two grooves 6 with two oil outlet 4c one_to_one corresponding, the bottom surface of two grooves 6 is parallel to each other, and the internal diameter that the beeline between two grooves 6 is less than oil-feed through hole 5a and oil return through-hole 5b. The rotating and limiting mechanism for limiting inner spool 2 slewing area it is additionally provided with, for the resetting-mechanism of inner spool 2 reset and the feedback mechanism for driving outer spool 3 to rotate between valve body 1 and inner spool 2. The bottom land of the groove 6 of the present embodiment is provided with the groove extended along its length.
The installing hole 10 that resetting-mechanism includes being arranged in valve body 1 and axis is vertical with spool chamber axis, installing hole 10 communicates with spool chamber, is provided with plug screw 11 and bayonet lock 12 that one end is stretched in spool chamber, is provided with spring 13 between plug screw 11 and bayonet lock 12 in installing hole 10.
