Abstract
A ripple diaphragm circulator includes a body inside which there is an internal chamber comprising an inlet opening and an outlet opening for fluid; and a flexible diaphragm placed in the chamber so as to be able to ripple there. The circulator further includes an actuating mechanism including at least one motor and a mechanical linking part linking the motor to the first edge of the diaphragm so as to move it in a reciprocating motion. The circulator also includes a device for detecting at least one value representative of a movement of the diaphragm, a power supply unit delivering an electrical power supply signal to the motor according to a detection signal.
Claims14
A ripple diaphragm circulator comprising:
- a body inside which there is a chamber internal to the body, this chamber comprising at least one inlet opening for flowing fluid into the chamber and at least one outlet opening for flowing fluid out of the chamber;
- a flexible diaphragm placed in the chamber so as to be able to ripple there between first and second edges of the diaphragm, the first diaphragm edge being located closer to the fluid inlet opening than to the fluid outlet opening and the second diaphragm edge being located closer to the fluid outlet opening than to the fluid inlet opening;
- the circulator further comprising:
- an actuating mechanism comprising at least one motor and at least one mechanical linking part linking the motor to the first edge of the diaphragm so as to move it in a reciprocating motion relative to the body in order to produce a ripple on the diaphragm propagating from the first diaphragm edge to the second diaphragm edge, wherein the circulator also includes a detection device for detecting at least one value representative of a movement of the first diaphragm edge relative to the body, the detection device being functionally linked to a motor power supply unit, this power supply unit being arranged to deliver at least one electrical power supply signal to the motor according to a detection signal delivered to the power supply unit by said detection device, this detection signal being dependent on said at least one detected value, the circulator further comprising a fluid deflector positioned in the chamber and connected to the body in order to direct fluid arriving in the chamber via the fluid inlet opening toward the first diaphragm edge in a direction running from this first diaphragm edge to the second diaphragm edge, said detection device comprising a sensor for detecting the movement of the first diaphragm edge, said sensor being attached to the fluid deflector.
