Fig. 1 is the utility model embodiment plan view.
Embodiment
As shown in Figure 1, specific embodiment of the utility model is a kind of boosting type multiposition cylinder, this cylinder is separated into 4 air chambers by 3 middle cover 8 with cylinder body, the cylinder body front end is provided with protecgulum 1, rear end of the cylinder block is provided with bonnet 2, and above-mentioned air chamber is made up of a control position air cavity 3 and 2 the supercharging air cavitys 4 that are arranged side by side and the air inlet chamber 5 that is arranged on supercharging air cavity 4 rear ends that are arranged in air cavity 3 rear ends, control position; Correspondence is provided with first piston 31 in the air cavity 3 of control position, and correspondence is provided with piston 41 in each supercharging air cavity 4, and these piston 41 1 sides form groove 411, and correspondence is provided with second piston 51 in the air inlet chamber 5, and these second piston, 51 1 sides form groove 511; Big piston bar 6 passes the first piston 31 in the control position air cavity 3, and big piston bar 6 front ends form actuating station 61, and rear end and supercharging air cavity 4 interior vent piston rod 7 are connected; Form the vent 71 that connects along its axial direction in the vent piston rod 7, vent 71 is terminal to be communicated with air inlet chamber 5, in vent piston rod 7, also offer with supercharging air cavity 4 in piston 41 and the vertical core 72 that is connected of the groove 511 on second piston 51 of air inlet chamber 5; On protecgulum 1, offer first inlet hole 11 and with control position air cavity 3 internal communication; Offer second inlet hole 81 and the 3rd inlet hole 82, the second inlet holes 82 and control position air cavity 3 internal communication respectively near the middle cover 8 of controlling position air cavity 3 one sides, the 3rd inlet hole 83 is communicated with the supercharging air cavity 4 of close control position air cavity 3 one sides; On bonnet 2, offer the 4th inlet hole 21, and be communicated with air inlet chamber 5.Between the endoporus of middle cover 8 and vent piston rod 7, be provided with Sealing 9.
This cylinder has 4 air cavitys, and the air cavity between first inlet hole 11 and second inlet hole 81 is between control position air cavity 3, the three inlet holes 82 and the 4th inlet hole 51 being 2 supercharging air cavitys 4 and an air inlet chamber 5.When 11 air inlets of first inlet hole, when cylinder runs to the supercharging position, 82 air inlets of the 3rd inlet hole, the supercharge cylinders motion, the 3rd inlet hole 82 was stopped the supple of gas or steam after work put in place, 51 air inlets of the 4th inlet hole, when cylinder was got back to the supercharging position, the air inlet area of first inlet hole 11 was bigger than the 4th inlet hole 51, so stop, last first inlet hole 11 is stopped the supple of gas or steam, and cylinder is got back to original position.
