Abstract (en)
[origin: EP1980729A1] The sprayer has a valve e.g. piston (2), cooperating with a main seat and a return spring (3), where the seat is formed in mass of a sprayer body (1) by a shoulder in an axial through-passage (12). A tubular guide liner (4) in the passage has a downstream liner section (4c) fixed in a downstream retaining section (1c) of the body beyond a radial outlet passage. An upstream section (4b) of the liner terminates in an upstream end (4a) that is axially set back from the seat towards downstream to define an annular fluid passage between the seat and a peripheral space.
