ELECTRICALLY-DRIVEN PUMP FOR MOTOR VEHICLE WINDSCREEN WASHERS

摘要

The invention relates to an electrically-driven pump for motor vehicle windscreen washers comprising a suction-impulse pump and an electric actuator which are disposed vertically and axially in relation to one another inside an essentially cylindrical casing (1) with an essentially cylindrical cover (2). The casing and cover are provided with sealing means (11) consisting of a peripheral groove (12, 13) having a concave cross-section. Moreover, said casing and cover are disposed such that the connection therebetween defines a housing that is adapted to house a seal ring (14).
