Patent number: 10724517Abstract: 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.Type: GrantFiled: April 6, 2017Date of Patent: July 28, 2020Assignee: DOSATRON INTERNATIONALInventors: Najib Laatiaoui, Christophe Charriere

Patent number: 10551227Abstract: Disclosed is a monitored proportional metering device including a liquid metering pump having an inlet, an outlet, a suction nozzle, and a mechanism for adjusting the flow in the nozzle. The metering device is also includes a detection assembly, the assembly including at least a unit for detecting the pressure variation in the nozzle, which unit is arranged between the first suction valve and the mixing chamber, a water meter at the inlet, a probe for measuring the level in the container of material to be suctioned, a unit for determining the position of the mechanism for adjusting the volume to be suctioned, and a man/machine interface for processing, recording, and displaying the data from the detection unit. Also disclosed are methods for monitoring a metering pump implementing the proportional metering device.Type: GrantFiled: July 13, 2016Date of Patent: February 4, 2020Assignee: DOSATRON INTERNATIONALInventors: Gregory Lucas, Christophe Charriere

Patent number: 9689765Abstract: A liquid metering pump includes an intake nozzle (2) provided with an intake valve (3) communicating with a working chamber (4) in which a piston (5) can be moved in an alternating translation movement, suction being produced, with the intake valve open, when the piston moves away from the nozzle, and delivery being produced, with the intake valve closed and liquid emerging through an outlet valve, when the piston moves towards the nozzle. The pump includes, between the intake valve (3) and the working chamber (4), a device (D) for detecting the variation in pressure, the device (D) including a duct (10), which is connected at one end to the working chamber (4) and is provided at its other end with the intake valve (3), and an element (11) which is sensitive to the pressure in the duct, the element (11) being mounted in the wall of the duct.Type: GrantFiled: September 28, 2011Date of Patent: June 27, 2017Assignee: DOSATRON INTERNATIONALInventors: Gregory Lucas, David Vacher, Christophe Charriere
