Abstract (en)
[origin: EP0718045A1] The pump (501), comprises a cylindrical body (503) defining a cylindrical pumping chamber (502) with an axis Y, and a first piston (507), having an operating plunger (506,) and supported against a return spring (509) is housed in the chamber. A cylindrical pre-compression chamber (505) having an axis Y has a second piston (510) supported against a second return spring (511). The two chambers are connected by a passage (550). A supply channel (504) has a non return valve (515,504a) which discharges into the pumping chamber. A delivery tube (517) has an atomising nozzle (520) connected by a delivery channel (518) to the pre-compression chamber. The pre-compression chamber has a slide (F) able to open and close the passage to the pumping chamber. When the pump is at rest the passage is closed, connection is established during pre-compression under the action of the operating part.
