FLUID-PRESSURE OPERATED SHOCK-ABSORBER Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: shock-absorber has housing with a guide, plunger received in the housing, and valve made up as a rod provided with a plate at one of its ends and piston at the other end. A diaphragm provided with an opening is mounted inside the housing. The diaphragm separates the housing into two spaces. The rod of the valve passes through the opening in the diaphragm for permitting overlapping it with the plate. The piston of the valve is set in the guide. The mechanism for moving the valve has a pair of links that are pivotally interconnected, slide pivotally connected with one of the links, and tie whose one end is pivotally connected with one of the links and the other one is connected with the pusher of the drive. Each link is provided with a stop mounted at the place of their pivotal connection for permitting interaction with each other. The free end of the other link is pivotally secured to the housing. The slide is connected with the piston of the valve. The shock-absorber may be provided with a reverse spring interposed between the housing and pusher along the axis of the pusher. The pusher may be made up as flare cartridge. The stops may be set eccentrically with respect to the pivoting joint of the link pair. EFFECT: improved shock-absorbing. 4 cl, 2 dwg
