Detailed description of the invention
Hereinafter describe and be used for disclosing this utility model so that those skilled in the art are capable of this utility model.Hereinafter retouch
Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modification.
As shown in Fig. 1～5, embodiment of the present utility model includes pressurized part 1, automatic reverse control valve 2, and connection is outside
High-pressure output port H, oil return inlet T and high pressure hydraulic fluid port P, and connect the drainback passage 100 of oil circuit and high-pressure channel 101；Supercharging
Parts 1 include that low-pressure plunger 12 and high-pressure plunger 11, high-pressure plunger 11 lower end are connected with low-pressure plunger 12 upper end, and at high-pressure column
The top of plug 11 forms high pressure chest 13, forms oil back chamber 14, formed below at low-pressure plunger 12 above low-pressure plunger 12
Low pressure chamber 15, high pressure chest 15 is connected with high-pressure output port H by the first check valve 3.
It is critical that, automatic reverse control valve 2 includes controlling spool 21, upper piston 22 and lower piston 23, control valve
The upper end of core 21 connects upper piston 22, and the lower end controlling spool 21 connects lower piston 23, under the cross-sectional area of upper piston 22 is more than
The cross-sectional area of piston 23, forms upper chamber 24 at upper piston 22, form lower chamber 25 at lower piston 23；Automatic reverse control
Valve 2 processed is provided with low pressure hydraulic fluid port A, low pressure hydraulic fluid port A and connects with low pressure chamber 15, and oil return inlet T connects with drainback passage 100, hydraulic oil
Mouth P connects with high-pressure channel 101；When controlling to move on spool 21, low pressure hydraulic fluid port A connects with oil return inlet T, high pressure hydraulic fluid port
P ends；When controlling spool 21 and moving down, high pressure hydraulic fluid port P connects with low pressure hydraulic fluid port A, and oil return inlet T is ended.
It addition, pressurized part 1 also has the first control runner 102 and oil return runner 103, first controls runner 102 passes through
First other road 104 of connecting connects with upper chamber 24；Under low-pressure plunger 12 moves to bottom state, first controls runner
102 connect roads 104 other with first connect；Under low-pressure plunger 12 moves to the top state, first controls runner 102 and oil return
Runner 100 connects；High-pressure channel 101 separates two-way, and the second check valve 4 of leading up to connects with high pressure chest 13, separately leads up to
Second other road 105 of connecting connects with lower chamber 25.
More smooth in order to work, the first other road 104 of connecting is by damping hole 5 and the low pressure oil of automatic reverse control valve 2
Mouth A connection.
In order to easy to assembly and simplification control the structure of spool, lower piston 23 is independent parts, the upper end of lower piston 23
Face and the lower surface laminating controlling spool 21, upper piston 22 is integrated part with controlling spool 21.
Taking out lower piston 23 for convenience, the upper surface of lower piston 23 also has screwed hole 231.
Operation principle and the process of the present embodiment are as follows:
With reference to Fig. 1, Fig. 2 and Fig. 4, supercharger is as follows by descending turn of up motor process:
Hydraulic pump outlet hydraulic oil flows in the lower chamber 25 of lower piston 23 by the second other connection road 105, upper piston
The upper chamber 24 of 22 is communicated with low pressure hydraulic fluid port A by the first other connection road 104 and damping hole 5, the upper chamber of upper piston 22
24 are in pressure release state all the time, because the pressure that controls at lower piston 23 is far longer than the control pressure at upper piston 22, although
The active area of lower piston 23 is less than the active area of upper piston 22, but automatic reverse control valve 2 duty is still within down
Position, i.e. low pressure hydraulic fluid port A connects with oil return inlet T, and high pressure hydraulic fluid port P ends, and such hydraulic oil will pass through the first check valve 3 and arrives upper height
Pressure chamber 13, promotes low-pressure plunger 12 to move down under high-pressure plunger 11 promotes, the hydraulic pressure in the lower low pressure chamber 15 of high-pressure plunger 11 compression
Oil, moves down into the end by low-pressure plunger 12, with the hydraulic oil of low pressure chamber 15 the most at present through the low pressure direct oil return of hydraulic fluid port A to drainback passage
100。
When low-pressure plunger 12 moves to bottom, hydraulic pump outlet hydraulic oil flows into upper high pressure through the first check valve 3
Chamber 13, and control runner 102 and first through first and other connect 104 and flow in upper chamber 24, partial high pressure oil is logical simultaneously
Cross in the lower chamber 25 that the second other connection road 105 flows into lower piston 23, the now control oil pressure of lower piston 23 and upper piston 22
Equal in magnitude, but owing to the area of upper piston 22 is more than the area of lower piston 23, the therefore control spool of automatic reverse control valve 2
21 can move down, i.e. the work of automatic reverse control valve 2 changes into upper, and high pressure hydraulic fluid port P connects with low pressure hydraulic fluid port A, such hydraulic oil
Will pass through high pressure hydraulic fluid port P and low pressure hydraulic fluid port A and arrive lower low pressure chamber 15, promote high-pressure plunger 11 under low-pressure plunger 12 promotes on
Moving, high-pressure plunger 11 compresses the hydraulic oil in high pressure chest 13, is increased by pressure, and the hydraulic oil simultaneously gone up in low pressure chamber 14 passes through back
The oil direct oil return of runner 103 is to drainback passage 100.
But owing to now high pressure hydraulic fluid port P communicates with low pressure hydraulic fluid port A, pressure oil will continue to add to upper work by damping hole 5
Plug 22, because of without making upper piston, at 22 because of pressure oil between high-pressure plunger 11 and the inwall of end cap clearance leakage and produce
The raw insecure problem of automatic reverse control valve 2, automatic reverse control valve 2 is continually maintained in upper state.
Reference Fig. 3,5 superchargers are as follows by up turn of descending motor process:
When low-pressure plunger 12 moves to upper end, first controls runner 102 connects the 104 upper low pressure chamber of connection with the first side
14, now the control oil of upper piston 22 will enter drainback passage 100 through oil return runner 103.The now control oil pressure of lower piston 23
Power is much larger than the control-oil pressure of upper piston 22, and therefore the control spool 21 of automatic reverse control valve 2 will be shifted up, i.e. automatic reverse
The duty of control valve 2 is switched to bottom, and low pressure hydraulic fluid port A is connected with oil return inlet T, high-pressure mouth P end, supercharger change into
Lower operation.
But owing to now low pressure hydraulic fluid port A communicates with oil return inlet T, upper chamber 24 connects with low pressure hydraulic fluid port A through damping hole 5 and lets out
It is pressed onto oil return inlet T, because of without being produced from the dynamic reversing control valve insecure problem of control.Automatic reverse control valve 2 continues to protect
Hold in the next state.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively
Planting changes and improvements, these changes and improvements both fall within the range of claimed this utility model.This utility model requirement
Protection domain defined by appending claims and equivalent thereof.
