Abstract
This delivery module includes: a pump for making the liquid flow; and an electronic circuit for controlling the pump. The delivery module further includes a channeling block having two channeling elements which define, when they are superimposed, channels for the liquid and which include: an inlet channel and an outlet channel.
Claims14
A delivery module, for delivering a liquid from a tank toward a downstream conduit in a motor vehicle, the delivery module comprising at least:
- a pump configured to make the liquid flow from the tank toward the downstream conduit;
- an electronic circuit connected to the pump and configured to control the pump;
- a channeling block comprising two half channeling elements which are configured to define, when they are superimposed, at least two channels in which the liquid circulates, the channels including at least:
- i) an inlet channel configured to channel the liquid toward the pump, and
- ii) an outlet channel configured to channel the liquid coming out from the pump,
- wherein the channeling block includes a fitting configured to fluidly connect an outlet of the delivery module to the downstream conduit and an inlet for fluidly connecting the delivery module to the tank, and
- wherein one of the half channeling elements presents at least one cavity configured to define at least one of the channels, and wherein another half channeling element is configured to seal said cavity when the half channeling elements are superimposed, and
- two joining members arranged so as to join the pump to the inlet channel so that the liquid can flow from the inlet channel toward the pump through a joining member and from the pump toward the outlet channel through a joining member.

- wherein one of the channeling elements presents at least one cavity configured to define at least one of the channels, and wherein another channeling element is configured to seal said cavity when the channeling elements are superimposed;
- and
- wherein both of the two channeling elements each comprise weld beads arranged around the at least one cavity defining the at least one channel, wherein the weld beads seal the at least channel when the two channeling elements are superimposed and facing weld beads are weld together.
