FIELD: automotive industry; suspensions. SUBSTANCE: proposed suspension shock absorber contains reservoir 11 formed by main tube 1 and additional tube 12 installed coaxially with main tube, piston 3 secured on rod 2, dividing piston 8, pump 5 located between piston 3 and dividing piston 8, valve 17 connecting rod space with reservoir 11. Pump 5 has two valves one of which, namely, valve 7, connects through channel 9 made in housing of pump 5, space between piston 3 and pump 5 with reservoir, and other valve 6 connects space between piston 3 and pump 5 with space between pump 5 and dividing piston 8. Pump 5 is furnished with spring-loaded pressure disk 14 with at least one rod 13 secured on disk. Working end of rod provided with cut engages with hole made in housing of pump 5. valve connecting rod space with reservoir 11 can be additionally connected with space between pump 5 and dividing piston 8, or with space between piston 3 and pump 5. Upper spring-loaded piston 20 with hole is installed in rod space. Buffer 23 is mounted on rod 2. EFFECT: reduced labor input in manufacture, improved reliability of device. 3 cl, 4 dwg |
