摘要:
A peripheral pump for feeding fuel from a supply tank to the internal combustion engine of a motor vehicle, in which, in a pump chamber (17) embodied by at least two adjacent walls (18, 19), a revolving circular-cylindrical impeller (12) is disposed, on whose face end in an intake-side wall (18) and an outlet-side wall (19) of a medium a feed conduit (41, 42) is provided, which communicate with one another at an angle (.beta.) via a radially disposed connecting conduit (49, 51) in the wall (18, 19) having a pressure region (34, 35) cooperating with the impeller (12), and these pressure regions (34, 35) can be acted upon by the pressure building up increasingly in the feed conduit (41, 42), thus bringing about an equalization of axial force with respect to the impeller (12) at the walls (18, 19) of the pump chamber (17).
