As shown in figure 5, when 3 oil inlet of work oil inlet, work 4 oil return of oil return opening, motor turning anticlockwise, GA, GB difference
For the pressure tap of work oil inlet 3 and the oil return opening 4 that works, overflow when the input pressure of work oil inlet 3 is buffered more than the first revolution
When flowing the set pressure of valve 7, the first revolution buffer overflow valve 7 opens overflow, and an overflow oil return part opens the second unidirectional repairing
Valve 5 returns to work oil return opening 4, and another part is returned directly to repairing mouth 8, and since work oil inlet 3 is high-pressure mouth, first unidirectionally mends
Fuel tap 27 will not be opened.When motor is braked, due to motor inertia, work oil inlet 3 is emptied generation negative pressure, passes through repairing mouth 8
And the first unidirectional Fill valve 27 is opened to 3 repairing of work oil inlet.When work 4 oil inlet of oil return opening, work 3 oil return of oil inlet, horse
Up to revolution clockwise, principle is the same as consistent counterclockwise.
The utility model additionally provides a kind of rotary motor, including above-mentioned rotary motor valve group end cap.Due to this reality
With novel rotation motor valve group end cap can effectively avoid motor braking when be emptied caused by noise and abrasion, accordingly
Ground, the utility model rotary motor also have above-mentioned advantageous effects, and details are not described herein.
The course of work of the utility model rotary motor is：When work 3 oil inlet of oil inlet, motor normal work not overflow
When, high pressure oil enters oil inlet oil duct by the oil inlet 3 that works, and then enters oil inlet waist type groove 14, motor by first flow 19
Oil return passes through oil return waist type groove 13, second flow channel 20, oil return oil duct and work 4 oil return of oil return opening.When motor has load pressure punching
When hitting, 3 pressure rise of work oil inlet is more than the first revolution 7 set pressure of buffer overflow valve, and the first revolution buffer overflow valve 7 is opened
Overflow is opened to buffer motor pressure impact, an overflow oil return part enters repairing oil by flowing the 4th runner 24 and third flow channel 23
The second unidirectional Fill valve 5 simultaneously is opened into oil return oil duct, since the oil inlet 3 that works is high-pressure mouth, the first unidirectional Fill valve 27 in road
It will not open；Overflow oil return another part directly passes through 8 oil return of repairing mouth.When motor is braked, work oil inlet 3 stops supplying
Oil, but due to motor movement inertia, motor will continue to turn round, and at this moment motor is in pump condition, and work oil inlet 3 is inhaled for pump condition
Hydraulic fluid port, work oil inlet 3 can be due to generating negative pressure for shortage of oil, at this moment meeting between 8 and first unidirectional Fill valve 27 of repairing mouth
There are pressure difference, the hydraulic oil of repairing mouth 8 can be mended by repairing oil duct and the first unidirectional Fill valve 27 of opening to work oil inlet 3
Oil.
In conclusion the utility model rotary motor valve group end cap has following advantageous effects：
First, repairing runner is short, when motor braking is emptied, can run through integrated valve group repairing mouth and carry out repairing, subtract
Lacked the repairing time, improved repairing efficiency, avoided noise caused by motor is emptied and abrasion, and reduce motor into return
Oil pressure loses, and reduces the risk of motor oil inlet and oil return oil leak, improves motor reliability；
Second, when motor has compression shock, revolution buffering overflow is opened, and overflow oil return by repairing mouth and can return simultaneously
Hydraulic fluid port connects fuel tank, improves motor revolution buffering spillover efficiency and reliability；
Third, revolution buffer overflow valve are installed with motor oil inlet and oil return mouth coaxial line, unidirectional Fill valve and motor oil inlet and oil return mouth
Right angle setting, it is compact-sized, the circumferential installation dimension of rotary motor is effectively reduced, convenient for whole machine installation, meets small-sized excavation
The characteristics of machine design structure is compact；
4th, inner flow passage is simple, and the pressure loss is small, effectively reduces processing cost；
5th, using cartridge-type buffer overflow valve and Fill valve, facilitate installation, interchangeability is good；
6th, integrated valve group is equipped with the dowel hole coordinated with motor shell, is conducive to integrated valve group and motor shell
Between cooperation.
Above in association with embodiment the embodiment of the utility model is described in detail, but the utility model not office
It is limited to described embodiment.For a person skilled in the art, in the principle and essence for not departing from the utility model
In the case of spirit these embodiments are carried out with a variety of variations, modification, equivalence replacement and modification to still fall in the utility model
