Abstract

917,660. Level-control valves for road vehicle suspensions. FABBRICA ITALIANA MAGNETI MARELLI. S.p.A.. May 15, 1959 [May 19, 1958], No. 16691/59. Class 108(2). Push rods 4, 4a adapted to lift inlet and exhaust valve members 5, 5a respectively, of a road vehicle pneumatic suspension levelcontrol valve, are actuated by a circular cam 11. The whole periphery of the cam comprises two respective tracks- 13, 14, corresponding respectively to the valve-opening and valve-closing positions of the push. rods. Specifications 865,937 and 876,165 are referred to.
