Patent number: 10935025Abstract: A pump assembly comprising a housing, a support frame that can be attached to the housing, and a rotor that can rotate within the housing. The housing consists of resilient material and comprises an interior surface, an inlet portion including an inlet for fluid, an outlet portion including an outlet for the fluid, and a diaphragm portion. A housing-engaging surface area of the rotor will form a sealing interference contact with the interior surface, and a chamber-forming surface area of the rotor disposed radially inward from the housing-engaging surface area will form a chamber with the interior surface. When the rotor rotates within the housing as in use, the chamber can convey fluid from the inlet portion to the outlet portion. The diaphragm portion will bear against the chamber-forming surface as the chamber-forming surface travels from the outlet to the inlet, to prevent fluid passing from the outlet to the inlet and to expel the fluid from the chamber through the outlet portion.Type: GrantFiled: February 8, 2017Date of Patent: March 2, 2021Assignee: QUANTEX PATENTS LIMITEDInventors: Richard Paul Hayes-Pankhurst, Jonathan Edward Ford

Patent number: 10495085Abstract: A pump comprising a housing and a rotor rotatably accommodated in the housing and having an axis of rotation. The housing comprises a resilient seal member, an inlet and an outlet for fluid. The rotor comprises first and second surface areas, and the rotor and housing are cooperatively configured such that the second surface area is radially recessed from the first surface area, forming a chamber with an interior surface of the housing, and the first surface area seals against the interior surface. The seal member is located azimuthally between the outlet and the inlet. The seal member will engage the first and second surface areas, operative to prevent the passage of fluid from the outlet to the inlet as the rotor rotates. An edge of the seal member is coterminous with an aperture through which the fluid can flow.Type: GrantFiled: March 17, 2016Date of Patent: December 3, 2019Assignee: QUANTEX PATENTS LIMITEDInventors: Richard Paul Hayes-Pankhurst, Jonathan Edward Ford

Patent number: 10465681Abstract: A pump comprises a housing, with an interior defining a rotor path, an inlet formed in the housing at a first position on said rotor path, an outlet formed in the housing at a second position on said rotor path spaced from said first position. A rotor is rotatable in the housing with a first surface that seals against the housing. A second surface is formed on said rotor circumferentially spaced from said first surface and forms a chamber that travels around said rotor path to convey fluid from the inlet to the outlet. A resilient seal formed with the housing is located on the rotor path to prevent fluid flow from said outlet to said inlet past the seal. A passage may be provided to supply fluid to an under surface of the seal at a pressure that acts to urge the seal against the rotor.Type: GrantFiled: September 22, 2015Date of Patent: November 5, 2019Assignee: QUANTEX PATENTS LIMITEDInventors: Richard Paul Hayes-Pankhurst, Peter William Ross

Patent number: 10087931Abstract: A pump is formed by a housing (10) having a fluid inlet (11) and a fluid outlet (12) and containing a rotor (15) forming with the housing (10) chambers (17a, 17b) that, on rotation of the rotor (15) by a drive, convey fluid from the inlet (11) to the outlet (12) to pump the fluid. A seal assembly (14) is arranged between the outlet (12) and the inlet (11). The seal assembly (14) includes a membrane (21) that contacts the rotor (15) and a flexible resilient spring member (22, 28, 35, 37, 40) that provides a force urging the membrane (21) against the rotor (15). The spring member (22, 28, 35, 37, 40) thus, on rotation of the rotor (15), moves radially relative to the axis of rotation of the rotor (15) and is arranged to provide a force on the rotor (15) via the membrane (21) that is constant and a minimum to maintain a seal between the rotor (15) and the seal (14) for a given outlet pressure of the pumped fluid.Type: GrantFiled: January 31, 2013Date of Patent: October 2, 2018Assignee: QUANTEX PATENTS LIMITEDInventor: Richard Paul Hayes-Pankhurst

Patent number: 9995296Abstract: A pump is formed by a housing (10) having an inlet (11) and an outlet (12) for a fluid. The housing (10) contains a rotator (13) provided with at least one surface recess (17a, 17b, 17c, 17d) that forms with an interior surface of the rotor a chamber (18a, 18b, 18c, 18d) that, on rotation of the rotor (13), conveys fluid from the inlet (11) to the outlet (12). A flexible seal (23) is provided on or as part of the housing (10) and is located between the inlet (11) to the outlet (12) to engage the rotor (13) to prevent fluid passing from the outlet (12) to the inlet (11). A second inlet (16) is provided leading to the outlet (12) for the supply to the outlet (12) of a second fluid and the second inlet (16) also supplies the second fluid to the back of the seal (23) to urge the seal (23) against the rotor (13).Type: GrantFiled: March 5, 2014Date of Patent: June 12, 2018Assignee: QUANTEX PATENTS LIMITEDInventors: Richard Paul Hayes-Pankhurst, Jonathan Edward Ford

Patent number: 9638204Abstract: A pump assembly comprises an inlet, an outlet and a housing having an inlet aperture in fluid connection with the inlet, and an outlet aperture in fluid connection with the outlet. A rotor located within the housing is shaped to form with an interior surface of the housing a chamber. On rotation of the rotor, the chamber conveys fluid from the inlet aperture to the outlet aperture. The housing carries a seal located in the inlet and urged into contact with the rotor to prevent the passage of fluid past the rotor from the outlet to the inlet. Center lines of the inlet and the outlet are parallel to one another. The outlet can be formed by linear movement of a mold core.Type: GrantFiled: October 15, 2013Date of Patent: May 2, 2017Assignee: QUANTEX PATENTS LTDInventors: Richard Paul Hayes-Pankhurst, Jonathan Edward Ford

Patent number: 9581157Abstract: A pump includes a housings and a rotor capable of rotating within the housing. The rotor engages an interior surface of the housing in use, with at least two radially-inward shaped surfaces on the rotor forming respective chambers with the interior surface. In use, the chambers transport fluid from an inlet in the housing to an outlet in the housing as the rotor rotates. A seal provided between the inlet and the outlet will engage each of the shaped surfaces to prevent fluid passing from the outlet to the inlet as each shaped surface travels from the outlet to the inlet. The rotor includes a surface portion extending axially and circumferentially between respective edges of the shaped surfaces. On planes normal to an axis of rotation of the rotor, the surface portion of the rotor has a greater curvature than that of the interior surface of the housing.Type: GrantFiled: October 4, 2012Date of Patent: February 28, 2017Assignee: QUANTEX PATENTS LIMITEDInventors: Richard Paul Hayes-Pankhurst, Jonathan Edward Ford
