Consult Fig. 3, the preferred embodiment of the utility model pneumatic type oil pressure suction booster 2 comprises makes moving cell 3, and this makes the air pressure feeding unit 4 of moving cell 3 to reach a connection.This is made moving cell 3 and comprise a cylinder body 31, a piston mechanism 38 that can move back and forth in this cylinder body 31, and a baffler 39 that is installed on this cylinder body 31.
One first cylinder cap 33 that this cylinder body 31 has a ring wall 32, be covered on these ring wall 32 opposite end respectively is arranged at this second cylinder cap 34 with one second cylinder cap 34, and is communicated with this strike the oil mouth 35 and laterally disposed oil outlet 36 on this second cylinder cap 34 in contrast to the strike the oil mouth 35, on the side of this first cylinder cap 33, and a containing space 37 that is matched and defined by this ring wall 32, this first cylinder cap 33 and this second cylinder cap 34.
This strike the oil mouth 35 has one away from the strike the oil pipe 351 of this second cylinder cap 34 with aspirated liquid force feed (not shown), and one can only be by the strike the oil one-way valve 352 of these strike the oil pipe 351 inflows for control hydraulic oil.And this oil outlet 36 has one away from the oil outlet 361 of this second cylinder cap 34 with output hydraulic pressure oil, and one can only be by the oil outlet one-way valve 362 of these oil outlet 361 outflows for control hydraulic oil.
This ring wall 32 is formed with first a switching hole 321 that is connected with this containing space 37, along these piston mechanism 38 movement directions and the second switching hole 322 separately, this first switching hole 321, and one first switch the relief hole 323 in hole 321 and 322 in this second switching hole between this, and this baffler 39 is to be installed on this relief hole 323.
This first cylinder cap 33 is formed with the first pore 331 of this containing space 37 of connection, and this second cylinder cap 34 is formed with the penetration hole 341 of this containing space 37 of connection, and one with this penetration hole 341 separately and be communicated with the second pore 342 of this containing space 37, this strike the oil mouth 35 is that the earthing that links to each other with this penetration hole 341 is installed on the side of this second cylinder cap 34 away from this first cylinder cap 33.
The distance that this first switching hole 321 and this first pore are 331 is less than the distance of this second switching hole 322 with this first pore 331.First to switch hole 321 are contiguous these first cylinder caps 33 for this, and this second to switch hole 322 are contiguous these second cylinder caps 34, therefore, this first distance of switching hole 321 and 33 of this first cylinder caps is less than the distance of 33 of this second switching hole 322 and this first cylinder caps.
This piston mechanism 38 has a piston 381 that is placed in this containing space 37, and an end is connected on this piston 381, and the other end places this penetration hole 341 and stretches into plunger booster bar 382 in the strike the oil mouth 35.
This air pressure feeding unit 4 comprises that one can provide the gas pressure source 41 of pressurized gas, and the pneumatic type transposition valve 42 of this gas pressure source 41 of a connection and this cylinder body 31.This pneumatic type transposition valve 42 has one and connects the pressure source interface 421 of this gas pressure source 41, the first working interface 422 of this first pore 331 of connection, the second working interface 423 of this second pore 342 of connection, the second control interface 425 that this first first control interface 424, that switches hole 321 of a connection connects this second switching hole 322, one first exhaust port 426 and one second exhaust port 427 that reach separately setting and be communicated with in the external world.
In this preferred embodiment, this pneumatic type transposition valve 42 is the four-hole two-position valves with one first exhaust port 426 and one second exhaust port 427, certainly, also can be to only have an exhaust port, still can reach identical effect.
Consult Fig. 3,4, utilize this pneumatic type transposition valve 42 can be in as shown in Figure 3 a primary importance, and mobile between as shown in Figure 4 a second place, with the flow path of the pressurized gas that switches this gas pressure source 41.
When this pneumatic type transposition valve 42 was positioned at primary importance, the piston 381 of this piston mechanism 38 was positions as shown in Figure 3, and this first switches the initial position in hole 321 block.At this moment, the pressurized gas that this gas pressure source 41 provides is via this pressure source interface 421, the first working interface 422, the first pore 331 and acting on the piston 381 of this piston mechanism 38, and then drive this piston 381 by initial position shown in Figure 3, move towards these the second cylinder cap 34 directions, to drive that this plunger booster bar 382 moves down and the hydraulic oil (not shown) that will be stored in this strike the oil mouth 35 is extruded with oil outlet 361 through the oil outlet one-way valve 362 of this oil outlet 36, utilize the rapid reduction of this piston 381 and plunger booster bar 382 basal areas, the hydraulic oil extruded by this oil outlet 361 is produced pressurized effect, and also can be through this second pore 342 between the gas of 34 of this piston 381 and this second cylinder caps, the second working interface 423 and being discharged by this first exhaust port 426.
This second switches end last in hole 322 during the position when this piston 381 moves to as shown in Figure 4 block, this piston 381 just can block this first switch hole 321, therefore, pressurized gas that this gas pressure source 41 provides is known from experience through this and first is switched hole 321 and this first control interface 424, and makes this pneumatic type transposition valve 42 move to as shown in Figure 4 this second place from this primary importance shown in Figure 3.
The pressurized gas that this gas pressure source 41 is provided diverted via by this pressure source interface 421, the second working interface 423, the second pore 342 and acts on the piston 381 of this piston mechanism 38, so drive this piston 381 by this end last the position move towards these the first cylinder cap 33 directions.
When this piston 381 when this end last, moved towards this initial position the position, this plunger booster bar 382 of meeting drive moves up and produces suction, and then utilize the strike the oil pipe 351 aspirated liquid force feeds of this strike the oil mouth 35, and institute's aspirated liquid force feed can be stored in this strike the oil mouth 35 through this strike the oil one-way valve 352, and the gas in this containing space 37 also can be discharged through this first working interface 422 and this second exhaust port 427.
And when the end last position of this piston 381 by Fig. 4, when moving to this initial position as shown in Figure 3, this piston 381 just can block this second switch hole 322, therefore, the pressurized gas that this gas pressure source 41 provides is known from experience through this second switching hole 322 and this second control interface 425, and makes this pneumatic type transposition valve 42 from this second place shown in Figure 4, moves to this primary importance as shown in Figure 3, borrow this piston mechanism 38 of above-mentioned action control to move back and forth, with cyclic suction, extrude hydraulic oil.
What this will specify be, the gas that this piston 381 may be carried secretly in movement then can be discharged by this relief hole 323, makes the movement of this piston 381 can be more smooth and easy, utilizes simultaneously this baffler 39 to lower the noise of exhausts.
In sum, the utility model pneumatic type oil pressure suction booster 2, utilize first on this cylinder body 31 to switch hole 321 and second and switch hole 322, the first control interface 424 with this pneumatic type transposition valve 42 is connected with the second control interface 425 respectively, therefore, only need pressurized gas with this gas pressure source 41 just can drive the movement between this initial position and this end last position of this piston mechanism 38, need not to use spring, not only unitary construction is simple, and can also provide the ultrahigh pressure of stablizing supercharging oil pressure, cooperate the control of pneumatic type transposition valve 42 can also avoid producing impact noise, so really can reach the purpose of this utility model.
