Title: The Innovative Mind of Philippe Duquennoy

Introduction

Philippe Duquennoy, based in Camarsac, France, is a notable inventor recognized for his contributions to engineering and fluid mechanics. With a total of seven patents to his name, Duquennoy has made significant strides in the development of metering mechanisms and diaphragm pumps.

Latest Patents

Duquennoy's latest innovations include a "Metering mechanism for a proportioning pump, and associated pump and usage method." This invention features a metering element that is translatably mounted in a jacket, which interacts with an adjusting sleeve through a screwing movement. This movement induces a translational shift in the metering element, equipped with a check valve on one end and a plunger on the other. The plunger's reciprocating motion facilitates suction and expulsion of liquid, effectively optimizing the metering process.

Moreover, he has patented a "Pump having a cap retaining a diaphragm in a receptacle." This diaphragm pump consists of a body with suction and discharge connections, as well as valves regulating flow. The diaphragm is strategically situated to enhance pump efficiency, with a control chamber that alternates between vacuum and pressure to operate effectively.
