ABSTRACT:
A lock-up clutch-for a hydrodynamic torque converter has a piston connectable to a converter housing through at least one friction lining and the piston is capable of a deflection movement in the axial direction. In the friction lining and in one of the piston or the converter housing, at least one depression is embodied for the passage of hydraulic fluid from the converter circuit. Associated with at least one of these depressions is an inflow and outflow, the former opening radially outside into the converter circuit and the latter opening radially inside into a chamber between the converter housing and the piston. The inflow depression and the outflow depression are both provided in one converter components, while a passageway depression is active in the adjacent converter component. The inflow or outflow depression runs, starting from the outer or inner circumference of the friction lining, at least into the extension area of the passageway depression, so that at least one fluid connection is established between the inflow and outflow depression and a passageway depression.
