Seitenkanalpumpe mit Seitenkanal im Ansaugdeckel zur Vermeidung verlustbehafteter Wirbelstrukturen

摘要

The invention relates to a side canal pump with a suction cover (10). The pump is used in a motor vehicle to deliver fuel. The suction cover (10) has a side canal (11) which runs radially around a rotation point (14) located in the suction cover (10), a first opening (13) for a suction canal (27) of the side canal (11), and a side canal width (BSK) which remains constant and which is located in a partial area running in a circumferential direction. The side canal (11) has a side canal width (BSK), said width remaining constant in the upper side (8), when seen from a beginning (12) of the side canal (11) with a starting value of a first angle ( phi ) ranging from 0 DEG , preferably of about 5 DEG , and no greater than 20 DEG , with regard to a line (LB) through the rotational axis (14) and through a contact point (1) located at the beginning (12). This results in an improved hot gasoline behavior, an increased efficiency, and a high pressure relationship of the side canal pump. The suction cover is especially suited for a double-flow side canal pump.
