Abstract: A bleed valve (1) for a pipe into which a non-return function is integrated. The bleed valve is preferably designed to be a thermal valve.

Abstract: A device for the hydraulic control of an automatic transmission, especially a continuously variable automatic transmission. The control system comprises a forward/reverse drive unit (4), which is controlled by way of at least a first and a second shifting component (5, 6). The shifting components (5, 6) are in turn controlled via at least two valves (7, 8, 17, 18, 20, 21), which are pressurized by way of a pressurized medium pump (9). A gear selector device (15) selection is made among at least a forward gear (D), a neutral gear (N) and a reverse gear (R), wherein the selector device (15) possesses a non-mechanical connection to the transmission control system.

Abstract: A hydraulic system for supply of the secondary circuit (S) of a continuously variable belt drive transmission of a motor vehicle is proposed in which there is provided for adjusting the pressure (p_S1) of the primary pulley (S1), a primary valve (PRIV) and the pressure (p_S2) of the secondary pulley (S2) a secondary valve (SEKV) which are respectively controlled by one pressure regulator (EDS_S1, EDS_S2) comprising one pressure-selector valve between the primary valve (PRIV) and the secondary valve (SEKV) the adjustment of which determines whether the primary or the secondary valve (PRIV, SEKV) adjusts the main pressure to be conveyed by the oil pump (P) of the hydraulic system and in which the oil is supplied to the secondary circuit (S) via the pressure-selector valve (DAV).
