摘要： Inside a vacuum pump (1) having a single vane (3), some spaces (9) between the single vane (3) and a body (2) or a cover of the pump (1) can cause a decrease of the performances of the vacuum pump (1). In order to improve the performances of such vacuum pump (1) having a single vane (3), the invention proposes to reduce said spaces (9) by means of a flexible element (22) including two arms (28 and 29). This flexible element (22) is arranged on at least one of the faces (13 and 14) of the single vane (3). The arms (28 and 29) can be flattened or straightened according to the space to be filled between the single vane (3) and the body (2) or the cover of the pump (1).
