Abstract
A proportional metering pump includes a hydraulic machine, a metering mechanism provided with a nozzle, and a unit for attaching the nozzle to the pipe for access to the cavity inside the hydraulic machine, including a securing ring mounted in rotation about one of the ends of the nozzle, a locking ring mounted so as to be able to translate along the longitudinal axis around the pipe for access to the mixing chamber and is pressed, in the direction of the metering mechanism, against a shoulder created on the access pipe by a spring, the securing ring and the pipe being able to engage following a screw connection at the end of which they are secured in rotation so as to prevent unscrewing of the securing ring. Also disclosed is a method for assembling and disassembling a metering mechanism on a hydraulic machine of such a pump.
