Benefits of technology

The present invention provides a fluid flow pump that minimizes head loss. The pump includes a movable part that moves back and forth in a chamber to cause fluid to flow. The pump has two valves that help to prevent fluid from leaking out of the chamber and minimize head loss during the pumping process. This design eliminates the need for an admission checkvalve, improving the efficiency of the pump and ensuring that it can self-prim without needing excessive force.

Problems solved by technology

Such checkvalves are parts that are subject to wear and that give rise to head loss.

Embodiment Construction

[0032]As mentioned above, the pump 100 of the invention includes a suction inlet 41 and a discharge outlet 42.

[0033]The pump includes a motor 46 that may be located either outside the chamber 44, as shown in FIG. 1a, or else inside the chamber, as shown in FIGS. 2 to 4.

[0034]In all embodiments, the motor 46 is mechanically connected to the movable part in order to be able to move it inside the chamber 44.

[0035]The pump 100 also has a first upstream lip 120a that is placed closer to the suction inlet 41 than it is to the discharge outlet 42, and a first downstream lip 121a that is placed closer to the discharge outlet 42 that it is to the suction inlet 41.

[0036]These first upstream and downstream lips 120a and 121a are placed between one of the sides of said movable part 45 and a first wall 44a of the chamber 44 so as to define a first space 123a between these first upstream and downstream lips 120a and 121a.

[0037]The arrangement of the lips defining the first passage 123a gives the...

Abstract

A fluid flow pump comprising a suction inlet, a discharge outlet, and a movable part inside the chamber. The pump includes circular first upstream and downstream lips such that: over a first portion of the movement of said movable part in the chamber, the circular first upstream lip then allowing free passage for fluid between the first space and the suction inlet; and that over a second portion of said movement, the circular first upstream lip provides sealing preventing fluid from passing to the suction inlet, the circular first downstream lip allowing fluid to pass from the first space to said discharge outlet and preventing fluid from passing to said first space.

Description

[0001]The present invention relates to the field of fluid flow pumps.BACKGROUND OF THE INVENTION[0002]Pumps are known that are provided with a chamber of volume that varies as a function of the movement of a part that is movable inside the chamber, the chamber being fitted with a checkvalve upstream from the chamber and with a checkvalve downstream from the chamber.[0003]When the volume of the chamber increases, the chamber is then in the suction, so the upstream checkvalve opens and the downstream checkvalve closes, with the fluid then being sucked into the chamber.[0004]When the volume of the chamber decreases, the chamber is then in compression, so the upstream checkvalve closes and the downstream checkvalve opens, with the fluid then being discharged from the chamber to a discharge outlet.[0005]Such checkvalves are parts that are subject to wear and that give rise to head loss.OBJECT OF THE INVENTION[0006]An object of the present invention is to provide a fluid flow pump that ca...
