<p>The invention relates to a rotary pump for use in particular in a continuously variable transmission. The rotary pump comprises a drive shaft (54) with a rotor (53), in radial grooves of which movable displacement elements (55) are disposed and slide along the radial inner side of a surrounding cam ring (56), forming variable pump chambers. The rotor is bounded at both long sides by end faces (57,58), an end plate (68) being provided with some play between at least one end face and the rotor. One or more seals (69) are provided between the end face (57) and the end plate (68), to seal the supply and/or discharge apertures of the pump in order to prevent leakages between the end plate and the end face.</p> |
