The air hydraulic shock absorber consists of a cylinder, rod, plunger, movable and fixed axle boxes, hydraulic seals, gas and hydraulic chambers and a profiled needle. The shock absorber is equipped with an optimizing hydraulic double-stage regulator consisting of an internal bush with holes that is attached to the wall separating two spaces in the hydraulic chamber and linked with the plunger of the air hydraulic shock absorber fitted onto which is an external bush with holes with possibility of movement relative to the internal bush. Both bushes are interconnected by a multistart thread with a helix angle exceeding the friction angle, they are also connected by a flexible component. The profiled needle connected to the rod of the air hydraulic shock absorber enters the hole in the external bush of the optimizing hydraulic hydraulic double-stage regulator.

(57) Abstract: Use: protection of objects from the intense shock vibration mechanical loads. The inventive shock absorber includes a housing with a guide that is inside the plunger, a valve in the form of a rod with a plate on one end and a piston at the other. Installed in the housing aperture with a hole, which divides it into two cavities. The valve stem is passed through the aperture with the possibility of overlap of the plate, and the piston valve is placed in the guide. The mechanism for moving the valve is pivotally connected between a pair of links, a slide pivotally connected with one link rod pivotally connected at one end with one of the links and the other with the plunger actuator. Each link is made with the focus set in place their swivel interoperable with each other. The free end of the other link pivotally attached to the housing and the slider is connected with the piston valve. The shock absorber may be provided with a return spring mounted between the housing and the plunger along the axis of the latter. The plunger may be made in the form of cutter. Stops can be installed eccentric relative to the hinge is, is ribarov, equipment, etc., allowing a limited degree of mechanical loads from the intense percussive impacts arising from blasting and seismic vibrations. The main elements of protection are pneumohydraulically. Known gidroaerotsentr, comprising a housing, a rod, pneumatic and hydroboost, piston [1]The closest in technical essence and achieved result is pneumonanthe, comprising a housing, placed in it the plunger, a valve in the form of a rod with a plate mounted at one end, and mechanism for moving the valve in the form of pivotally interconnected links and slider, hinge associated with one link [2] The disadvantages of the known devices is the lack of controlled locking rod relative to the housing, which limits its application in systems amortization of interest, where there is a need for high-speed (up to 1 sec) the locking of depreciable object to produce it repair and other work that does not provide pre-tensioning rods of known absorbers. The present invention eliminates this disadvantage. This is achieved by de rod with the plate, installed on one end, and mechanism for moving the valve in the form of pivotally interconnected links and slider, hinge associated with one element, provided with a diaphragm with a hole that divides the body into two cavities in the casing guide, valve has a piston mounted on the free end of the rod passing through the aperture with the possibility of overlapping his plate, a piston accommodated in the guide, the mechanism for moving the valve has an additional rod, one end of which is pivotally connected with one of the links and the other with the plunger actuator, each link is made with emphasis, established in the place of their swivel interoperable with each other, the free end of the other link pivoted in the housing, and a slider connected to the piston valve. The shock absorber may be provided with a return spring mounted between the housing and the plunger along the axis of the latter. The plunger may be made in the form of cutter. In Fig.1 shows a General view of the pneumatic-hydraulic shock absorber of Fig. 2 position of the parts of the shock absorber after closing of the valve of Fig. 3 external element 1 in Fig. 2. A pneumatic shock absorber includes a housing 1, motion of the valve in the form of a hinge 6, connecting links 7 and 8 with the lugs 9, the separating diaphragm 10 with an opening 11, the guide 12 which is placed in the piston 5, the rod 13, one end of which is pivotally connected with one of the links and the other with the plunger 14 of the actuator 15, the return spring 16, the actuator 15 may be made in the form of the actuator 17, the outer cylinder 18, the hydraulic cavity "A" gas chamber "B" of compressed air. Hydraulic cavity "A" and a gas chamber B is communicated through the opening 11. The rod 3 is passed through the hole 11 and its piston 5 is hermetically installed in the guide 12 with the possibility of axial movement. In the initial position, the valve is normally open and is prevented from closing element 7, which is pivotally attached to the housing 1 and connected through a Central hinge 6 link 8 pivotally connected to a piston 5 with the plate 4. The transfer mechanism is held in position due to the eccentrically positioned relative to the Central hinge lugs 9 on the links 7 and 8 and return spring 16 that communicates with the link 8 through the plunger 14 and the intermediate link. When the locking of the shock absorber is controlled ignition of the actuator 17 and formed Gazi link pushes the link 8, and thereby the transfer mechanism "is" in the Central hinge 6 in place of articulation of the links 7 and 8. Under the action of compressed gas in the pneumatic cavity "B" of the shock absorber piston 5 with the plate 4 is moved and the plate 4 closes the opening 11 in the diaphragm 10, thereby isolating the pneumatic cavity "B" from the hydraulic cavity "A". Working slurry, a closed hydraulic cavity "A", prevents movement of the plunger 2, resulting in a controlled locking pneumatic-hydraulic shock absorber. For re-work and subsequent locking of the shock absorber 5 plate 4 returns to its original position, while the force of the spring 16 through the plunger 14 and the intermediate parts 7 and 8 are mounted on the lugs 9 and the shock absorber becomes rastopirenimi, ready for subsequent work. As can be seen from the above, performance shock absorber with a controlled closing of the valve allows instant stopping of the shock absorber without creating additional units locking shock-absorbing objects. All this simplifies the system locking, increases reliability, and improves performance. 1.
