In order to make the left cavity of hydraulic jack better more effectively be vented, further, described first through hole, the second through hole and first row pore are mutually vertical between two.
In order to make the right cavity of hydraulic jack better more effectively be vented, further, described third through-hole, fourth hole and second row pore are mutually vertical between two.
The beneficial effects of the utility model are: the utility model is convenient to the hydraulic jack of exhaust in the running, gas in left cavity is discharged by the first through hole, the second through hole, first row pore and exhaust pressure measuring tie-in, gas in right cavity is discharged by third through-hole, fourth hole, second row pore and exhaust pressure measuring tie-in, gas can be discharged in any installment state by oil cylinder effectively, avoids the more difficult and problem that causes gas to enter oil cylinder to cause oil cylinder and whole hydraulic system to tremble at work and creep of vent ratio.
