    • A vane for a displacement pump comprising a body (1), a profiled pumping chamber (2) defined within said body (1), and a rotor (4) rotatably mounted within said body (1), eccentric with respect to the pumping chamber (2) and carrying a vane (5) whose end portions slide against the inner surface (3) of the pumping chamber (2), characterized in that each operating end portion of the vane (5) is formed by a tilting tip (9) having a coupling means (11) articulated with respect to the vane body (5) and suitable for tilting within a limited field with respect to the vane body (5), the shape of the tip (9) and the allowed tilting field being such that the tilting tip (9) is applied against the inner surface (3) of the pumping chamber (2) when the vane (5) is rotated in a preestablished working direction (F1), and being such that the tip (9) is allowed to retract from the inner surface (3) of the pumping chamber (2) when the vane (5) is rotated in the direction (F2) opposite to the preestablished operating direction (F1). The invention also concerns a rotary displacement pump comprising at least a vane with tilting tips.

    • The invention relates to a vacuum pump (110, 210), in particular a single-vane vacuum pump for a motor vehicle engine, that advantageously allows to achieve a reduced wear of the end portions (122a, 122b, 222a, 222b) of the vane (120, 220) mounted on the pump. In particular, the vacuum pump comprises a stator (12), a chamber (14) defined inside said stator (12), said chamber (14) having a side wall (16.) whose transversal section has a predetermined shape,.a rotor (18) mounted in said chamber (14) and, capable of rotating around a rotation axis (0) parallel to said side wall (16), and a vane (120, 220) mounted on said rotor (18) and free to slide in a direction at right angles with respect to the rotation axis (0) of said rotor (18), said vane (120, 220) having a predetermined length (L2) and two opposite end portions (122a, 122b, 222a, 222b) that slide along the side wall (16) -of said chamber (14). According to the invention, at least one of said end portions (122a, 122b, 222a, 222b) of said" vane (120, 220) comprises. at least a part. (124) having a bend radius (R3) equal to that of a part (126) of said side wall (16).
