Problems solved by technology

This linear relationship will mean that while the minimum force will be just enough to provide a seal at a given outlet pressure, the maximum force will greatly exceed the force required to seal at the same outlet pressure
The increased friction also increases the heat generated between the housing and the rotor when the rotor rotates, which can be disadvantageous, especially if said part is made of plastic material
This generation of heat is also disadvantageous in medical applications, this heat may be transferred to the fluid being pumped and this can affect the properties of the fluid being pumped

Embodiment Construction

[0018] first reference figure 1 , the first pump is formed by a housing, indicated generally at 10, which may be formed by molding a plastic such as polyethylene or polypropylene. The housing 10 is formed with an inlet 11 for connection to a fluid source and an outlet 12 for the pumped fluid. The inside of the housing 10 is cylindrical. The part of the inside of the housing 10 between the outlet 12 and the inlet 11 (in figure 1 seen in clockwise direction) carries the seal assembly 14 described in more detail below.

[0019] The housing 10 accommodates a rotor 15 . The rotor 15 may be formed from corrosion resistant metal or as a precision injection molded plastic part formed from a resin such as acetyl. The rotor 15 is shaped as described in PCT / GB05 / 003300 or PCT / GB10 / 000798, with recessed surfaces 16a, 16b forming cavities 17a, 17b with the housing 10 .

[0020] Rotor 15 in figure 1 Rotate clockwise by a driver (not shown in the drawings). The housing 10 is formed wi...

Abstract

A pump formed by a housing (10) having a fluid inlet (11) and a fluid outlet (12) and housing a rotor (15) which is connected to the housing (10) Chambers (17a, 17b) are formed which convey fluid from the inlet (11) to the outlet (12) for pumping the fluid when the rotor (15) is rotated by the drive. A sealing assembly (14) is disposed between the outlet (12) and the inlet (11). The seal assembly (14) includes a membrane (21) in contact with the rotor (15) and a flexible resilient resilient member (22, 28, 35, 37, 40) providing a force urging the membrane (21) against the rotor (15). Thus, when the rotor (15) rotates, the elastic members (22, 28, 35, 37, 40) move radially relative to the axis of rotation of the rotor (15) and are arranged to rest on the rotor (15) via the membrane (21) Provides a constant and minimum force to maintain the seal between the rotor (15) and seal (14) for a given outlet pressure of the pumped fluid.

Description

technical field [0001] The present invention relates to pumps. Background technique [0002] From PCT / GB05 / 003300 and PCT / GB10 / 000798 it is known to provide a pump formed by a housing having a fluid inlet and a fluid outlet and housing a rotor which forms a chamber with the housing, in which case the drive As the rotor rotates, the chambers pass fluid from the inlet to the outlet to pump the fluid. It needs to be ensured that fluid cannot be transferred from the outlet to the inlet in the direction of rotor rotation. For this purpose, PCT / GB05 / 003300 and PCT / GB10 / 000798 disclose the use of a seal arranged between the outlet and the inlet, said seal being in contact with the rotor for this purpose. [0003] Since the rotor has cavity-forming surfaces radially inward of the housing, it is necessary for the seal to move radially inward and outward relative to the axis of rotation of the rotor in order to maintain contact between the seal and those rotor surfaces to prevent F...
