  • Patent number: 8403293
    Abstract: A ball valve (10) for sealing a conduit (12) is described. The ball valve includes a housing having a throughbore and a valve seat. An apertured ball element (18) is mounted within the housing and is rotatable about an axis of rotation (38) between a throughbore open and a throughbore closed position. The apertured ball element (18) has a first portion (20) and a second portion (22) coupled together which are rotatable and moveable relative to each other. The first portion has a sealing surface for engaging with the valve seat. In use, in the throughbore closed position, the second portion is moveable relative to the first portion to axially displace the first portion from the axis of rotation towards the valve seat such that the sealing surface on the first portion of the apertured ball forms a seal with valve seat.

  • Patent number: 7762526
    Abstract: A Pendulum Valve having Independently and Rapidly Controllable Theta- and Z-axis Motion. The valve actuator used in the present invention provides the benefit of wide open unrestricted flow of a pendulum valve coupled with the high-resolution and wide dynamic range flow throttling of a ball or butterfly valve. The actuator mechanism will include motor drives and associated control system so that the drives are closely coupled to give highly controlled motion. The drive assembly introduces a concentric shaft arrangement that, when coupled with the highly controllable motor drives, exploits a cam-follower arrangement to make the relative rotation between the two concentric shafts result in highly controlled theta and z-axis motion. Finally, the plate to seal spacing afforded is greater than previously possible with prior valve actuator mechanisms, thereby substantially reducing flow turbulence through the valve as the valve plate eclipses the valve ports.

  • Patent number: 6412750
    Abstract: A valve system for fluid pipes is disclosed. This valve system is designed to be operable using pneumatic pressure or using another means, such as a valve control lever or fluid pressure, in place of pneumatic pressure and is designed to be controlled easily and precisely. The valve body (20) is thus movable within the passage (13) while minimizing frictional force between the valve body and the valve housing (10). The valve control lever (50) is operated in conjunction with the annular guide groove (24) formed on the circumferential external surface of the pressure actuated flange (25) of the valve body (20). In such a case, the linear moving direction and moving distance of the valve body is determined by the rotating direction and rotating angle of the lever (50). The valve system of this invention also has a rotor (40) used for centrifugally forcing the fluid introduced into the passage. A fluid guide rod (45) axially extends along the center of the passage, thus guiding the flow of fluid.

  • Patent number: 3985335
    Abstract: This invention relates to a ball type shut off valve. The valve includes a body having a flow passage therethrough defining a seat. A ball is loosely held within the flow passageway by the two ends of a shaped, flat strip spring which is held in a longitudinal diametral slot, in a cylindrical shaft positioned in and sealed to the body, with the axis of the shaft at right angles to the longitudinal axis of the body, and to the flow path of the fluid. Rotation of the shaft causes the strip spring to rotate and to control the position of the ball relative to the seat. Rotation in one direction causes a first end of the spring to move the ball away from the seat. Rotation of the shaft and the spring in the other direction causes the second end of the spring to move onto the sea and to hold the ball against the seat by the compliance of the second end of the spring.
