Abstract (en)
[origin: EP0707894A1] The pump consists of a cylindrical body (1) with a lower intake (2) and inlet valve (12), a collar (6) to retain a spring (5) and a piston (2) with a nozzle (3) which has its outlet channel controlled by a valve (4). The nozzle has an inner shoulder (33) at its upper end, and a lower end which broadens beneath the collar, forming a cap (30) which engages with the upper end of the piston (2) to form an inner chamber (26) containing the outlet valve(4). The lower part (22) of the piston has an axial channel (23) which acts a seat for the outlet valve. The outlet valve (4) and its spring (41) are fitted into the nozzle from its lower end before the piston is fitted.
