Housing container for fuel delivery pump of vehicle

摘要

The container has a feed aperture for back-flowing fluid issuing in container interior. In the container interior a part ring-shaped flow channel (17) concentric to the container axis is formed at an axial distance from the container base (11). The commencement of the channel is connected to the feed aperture. The inner channel wall (171) in a radial direction has a number of through passage slots (19) arranged spaced apart over the channel length. Their lower slot edges (191) located near to the container base (11) are on or near the channel base (172). The axial width of the through passage slot when viewed in the direction of the container axis (101) is very much smaller than the axial height of the flow channel (17) when viewed in the direction of the container axis.
