The piston channel of hydraulic cavities, the interior sliding of the piston channel are equipped with piston shaft, it is characterised in that: the piston shaft and piston channel
Between be equipped with gap, which forms respiration channel, and be equipped in piston channel the pressurized seal Y-shaped ring of corresponding atmospheric pressure cavity with it is right
The hydraulic packing Y-shaped ring for answering hydraulic cavities is equipped with piston shaft guide sleeve between pressurized seal Y-shaped ring and hydraulic packing Y-shaped ring, described
Exhaust passage is additionally provided on valve body, the respiration channel between pressurized seal Y-shaped ring and hydraulic packing Y-shaped ring passes through with the valve body external world
Exhaust passage connection.
The inner lip and outer lip of the pressurized seal Y-shaped ring are equipped with wave shape groove, and storage in wave shape groove
Lubricating grease.
The inner lip of the hydraulic packing Y-shaped ring is equipped with wave shape groove, and storing lubricating grease in wave shape groove.
Respiratory cavity is equipped in piston channel between the pressurized seal Y-shaped ring and hydraulic packing Y-shaped ring, respiratory cavity is to set
The annular groove on piston channel inner wall is set, annular groove is connected to exhaust passage.
The exhaust passage is diagonally disposed, and the annular groove is equipped with the guide groove radially extended, and guide groove and exhaust passage connect
It is logical.
The beneficial effects of the invention are as follows the improved clutch boosters with plunger gas-liquid sealing structure, can be effective
It prevents from being mixed into the reduction hydraulic packing Y-shaped ring service life of hydraulic shock caused by air due to brake fluid；Pressurized seal Y-shaped ring with
Guide sleeve is set between hydraulic packing Y-shaped ring, the inner lip of pressurized seal Y-shaped ring and hydraulic packing Y-shaped ring can be reduced because of pressure
Abrasion caused by contracting amount is uneven.
Detailed description of the invention
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the portion the A enlarged drawing of Fig. 1 of the present invention.
Fig. 3 is the radial cross-section of respiratory cavity of the present invention.
Fig. 4 is the structure chart of pressurized seal Y-shaped ring of the present invention.
Fig. 5 is the structure chart of hydraulic packing Y-shaped ring of the present invention.
Specific embodiment
Attached drawing illustrates structure of the invention, further illustrates it in relation to details in conjunction with attached drawing below.The band plunger type
The clutch booster of gas-liquid seal structure includes valve body 1, and atmospheric pressure cavity 2, hydraulic cavities 3 and perforation gas are equipped in the valve body 1
The piston channel 4 of chamber 2 and hydraulic cavities 3 is pressed, sliding is equipped with piston shaft 5 in the piston channel 4, and the piston shaft 5 and piston are logical
Gap is equipped between road 4, which forms respiration channel 6, i.e., 5 outer diameter of piston shaft is slightly less than 4 internal diameter of piston channel, and piston is logical
The pressurized seal Y-shaped ring 7 of corresponding atmospheric pressure cavity 2 and the hydraulic packing Y-shaped ring 8 of corresponding hydraulic cavities 3 are equipped in road 4, in piston channel 4
The mounting groove of Matching installation pressurized seal Y-shaped ring 7 Yu hydraulic packing Y-shaped ring 8, pressurized seal Y-shaped ring 7 and liquid are respectively equipped on wall
5 guide sleeve 9 of piston shaft is equipped between means of press seals Y-shaped ring 8, guide sleeve 9 is embedded on 4 inner wall of piston channel, the setting of guide sleeve 9
The small beat of piston shaft 5 can be reduced, cause the inner lip decrement of pressurized seal Y-shaped ring 7 and hydraulic packing Y-shaped ring 8 uneven
It is even, there is the risk of eccentric wear, exhaust passage 10, pressurized seal Y-shaped ring 7 and hydraulic packing Y-shaped ring 8 are additionally provided on the valve body 1
Between respiration channel 6 and the valve body external world be connected to by exhaust passage 10.The wherein setting energy of respiration channel 6 and exhaust passage 10
It enough avoids forming negative pressuren zone in corresponding piston channel 4 between pressurized seal Y-shaped ring 7 and hydraulic packing Y-shaped ring 8, so that part
Gas by entering negative pressuren zone in atmospheric pressure cavity 2 enters in hydraulic cavities 3 under the action of negative pressure.
The inner lip 71 of pressurized seal Y-shaped ring 7 nearby be arranged wave shape groove, can storing lubricating grease, reduce air pressure it is close
It seals Y-shaped ring inner lip 71 to wear, improves pressurized seal Y-shaped ring service life；Wave is arranged in the outer lip 72 of pressurized seal Y-shaped ring 7
Shape wave groove, can storing lubricating grease, play the role of auxiliary seal, while can prevent extraneous magazine from entering atmospheric pressure cavity 2.
Wave shape groove is nearby arranged in the inner lip 81 of hydraulic packing Y-shaped ring 8, can storing lubricating grease, prevent breathing logical
Gas enters inside hydraulic cavities in road 6, plays the role of auxiliary seal.
Respiratory cavity 41, breathing are equipped in piston channel 4 between the pressurized seal Y-shaped ring 7 and hydraulic packing Y-shaped ring 8
Chamber 41 is the annular groove being arranged on 4 inner wall of piston channel, and annular groove is linked together with respiration channel 6, and annular groove and exhaust are logical
Road 10 is connected to, and increases the gas reserves in respiration channel 6.
The exhaust passage 10 is diagonally disposed, and the annular groove is equipped with the guide groove 42 radially extended, guide groove 42 and exhaust
Channel 10 is connected to, and makes full use of limited space on valve body 1 that the arrangement of channel 10 is exhausted, and the setting of guide groove 42 can make to arrange
Gas channel 10 is staggered with hydraulic packing Y-shaped ring 8, when avoiding getting through exhaust passage 10, punches hydraulic packing Y-shaped ring 8, causes tight
It loses again, the program is realized by setting guide groove rather than expands annular groove, and the influence to body strength can be reduced.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
