Abstract

1378910 Change-speed gear GKN TRANSMISSIONS Ltd 22 March 1973 [18 March 1972] 13730/73 Divided out of 1378909 Heading F2D The subject-matter is the same as that of the main Specification but the claims are directed to the check valve 65 and control valve 54, which, together with the solenoid valve 60, control the supply of oil pressure to the cylinder 35 of the brake which establishes the planetary ratio.
