Patent number: 6729864Abstract: A stator (1) has a circular cylindrical internal surface (3) delimiting an operating chamber. A rotor (4) is mounted so as to be rotatable about the axis (8) of the internal surface (3) and has a cylindrical external surface (11), with one generatrix (13) adjacent to the internal surface (3), a diametrically opposite generatrix being spaced from the internal surface. A sealing member (17), projecting through a slot in the stator (1) into the operating chamber and being movable substantially radially, has an axial length substantially equal to that of the rotor (4). The sealing member (17) is connected to the rotor (4) by a linkage which causes the radially inner end of the sealing member to closely follow the external surface (3). A shutter disc (6) at one end of the rotor (4) covers a port (14), in particular an inlet port, in the stator (1).Type: GrantFiled: January 8, 2003Date of Patent: May 4, 2004Assignee: E. A.

Patent number: 6120272Abstract: A pump or motor 10 provides a housing 20 which carries one or more elliptical drivers 40 which rotate freely with an axle which is rotatably carried by the housing. One V-shaped rocker 60 is associated with each elliptical driver, and moves in an oscillatory motion in response to being driven by the associated elliptical driver. When used as a motor, fluid entering the housing tends to apply pressure to one side of the elliptical driver, while the other side is shielded from pressure by the V-shaped rocker. Uneven pressure causes the elliptical driver to rotate. As the elliptical driver rotates, the V-shaped rocker oscillates in a period manner at twice the frequency of the elliptical driver. The vertical height of the V-shaped is determined by an adjustable support 80, which allows regulation over the friction level and fluid seal between the rocker and the elliptical drive, and which allows adjustment to compensate for wear of the surfaces of contact between the rocker and the elliptical driver.Type: GrantFiled: August 10, 1998Date of Patent: September 19, 2000Inventor: Arturo Gallardo

Patent number: 6065874Abstract: Prior art linear bearings generally have a roller element which, in such a reciprocating motion application, tend to creep or slide along the surfaces upon which they roll. This is due to unequal frictional forces between the rolling surfaces. The linear bearing of the present invention substantially prevents straying and/or sliding of roller elements, and therefore provides bearing functionality at high speeds and great loads with longer longevity and reliability. The linear bearing can be used in many engineering applications, such as in a rotary engine, for example.Type: GrantFiled: August 26, 1997Date of Patent: May 23, 2000Inventor: Benjamin Tour

Patent number: 6000921Abstract: A fluid pump for transferring liquid material from one container to another is provided. The fluid pump is of a novel structure which comprises a circular base having a less diameter annular projection at a central portion and first guide slot radially formed through the body, an external annulus having a pair of second guide slots made in registry with the first guide slot to define a rectangular space therebetween for facilitating a slider to slide thereabout; a rotary disk disposed into the annulus including a plunger and pushing rod at under side for synchroneously sliding in a fluid channel and actuating the slider to move about so as to repeatedly alter the vacuum state in the pump for sucking the liquid material from one container and simultaneously discharging the sucked liquid material to another container.Type: GrantFiled: July 3, 1997Date of Patent: December 14, 1999Inventor: Gene-huang Yang

Patent number: 5885065Abstract: A pump for pumping a liquid containing solids comprises a housing having a first end and second end and an interior pump chamber. An inlet pipe leads to the pump chamber through the first end, and an outlet pipe leads from the pump chamber at the second end. A core having a vane extending therefrom rotates within the chamber. The core has hollow portions permitting material to move from the inlet pipe to the pump chamber and from the pump chamber to the outlet pipe. The vane extends from the core outwardly, seals against the housing, and works in cooperation with a pair of moving blades to draw material from the inlet pipe and expel the material through the outlet pipe. The blades, which are arcuate in shape and have curved ends, are operated by pneumatic cylinders and move from a retracted position in which they are positioned out of the pump chamber to a deployed position in which the curved end sealably engages the core.Type: GrantFiled: February 19, 1997Date of Patent: March 23, 1999Inventor: Marshall Long

Patent number: 5713732Abstract: A rotary compressor is provided, including: a housing containing a rotor having a compression eccentric and an axial shaft; a removable combination intake and exhaust manifold for conveying fluid into and out of a compression space formed between the compressor housing, the compression eccentric, and a removable combination dynamic seal and fluid channeling assembly which is securable between the manifold and the housing. The combination dynamic seal and fluid channeling assembly retains a dynamic seal in continuous contact with the compression eccentric and directs fluid into and out of the compression space. After being introduced through an intake port of the manifold, fluid is transferred past the combination dynamic seal and fluid channeling assembly, through a seal-engaging channel in the housing and into the compression space, where it is compressed via rotation of the compression eccentric about the axial shaft.Type: GrantFiled: March 31, 1995Date of Patent: February 3, 1998Inventor: Ross W. Riney

Patent number: 5707224Abstract: A liquid pump comprises generally a base, an annular ring including a pair of ingresses and a pair of egresses alternately formed on opposing circumferential walls aside a pair of rectangular recesses therebetween and defining a fluid channel between the base and itself, first and second swivel disks including a rotary plunger and a pushing rod on their under sides and rotating inversely inside the pump. An elongate slider sliding to and fro in a rectangular groove coactes with the rotary plunger for repeatedly changing the vacuum circumstances in the channel to synchronously suck and discharge the liquid material from one container to another.Type: GrantFiled: October 8, 1996Date of Patent: January 13, 1998Inventor: Gene-Huang Yang

Patent number: 5579733Abstract: A rotary motor with a pair of abutments that move relative to a rotor through the rotation of gears operatively connected to both the abutments and the rotor. The abutments and rotor are located within a housing such that the inner cavity of the housing is divided into four chambers. The rotor has a pair of blade sections that are in constant contact with the motor housing, so that the chambers are always sealed from each other. Also connected to the housing are a pair of intake ports and a pair of exhaust ports. The rotor rotates within the inner cavity pushing air from the intake ports to the exhaust ports. The abutments are constructed to move in a linear direction, to allow the blade sections to rotate from one chamber to another. The movement of the abutments is synchronous with the rotation of the rotor, so that the abutments are always in contact with the rotor to insure that there is negligible fluid communication between chambers.Type: GrantFiled: February 22, 1993Date of Patent: December 3, 1996Inventor: Benjamin Tour

Patent number: 4023540Abstract: An internal combustion engine of the rotary type which includes a cylindrical rotor having a skirt portion, rotating in an annular chamber, that comprises two arcuate walls of differing radii joined by relatively short, diametrically disposed sloping portions that serve as pistons. A sliding divider which extends through the annular chamber and the skirt portion establishes, with the sloping skirt portions, sub-chambers in the annular chamber in which compression of a combustible gas mixture and combustion of the mixture take place, the latter producing power for moving the rotor and the power shaft attached thereto. The divider is provided with longitudinallly spaced slots in which the rotor skirt is engaged whereby the divider is reciprocated as the sloping portions of the skirt pass through the slots.Type: GrantFiled: April 15, 1976Date of Patent: May 17, 1977Inventor: Hans Zollenkopf
