  • Pneumatic control valve
    Patent number: 9822709
    Abstract: A control valve for a gas turbine engine air starter. The control valve includes a spherical or ball valve element rotatable between a closed position and an open position to connect an internal flow passage to the air starter. A series of camming elements interconnecting a piston and a valve stem for the spherical valve element convert linear displacement of the piston into rotational movement of the valve for rapid opening.

  • PNEUMATIC CYLINDER WITH PRESSURE MODERATOR
    Publication number: 20130305916
    Abstract: A fluid cylinder assembly including a cylinder, a rod assembly, and a valve assembly. The rod assembly includes a rod having a first end and a second end and a piston connected to the first end of the rod. The piston is slidingly positioned in the cylinder. The second end of the rod extending from the cylinder. The valve assembly is in fluid communication with the cylinder. The valve assembly is configured to moderate pressure within the cylinder when an external force is applied against the second end of the rod.

  • Parts gripper
    Patent number: 6123375
    Abstract: A parts gripper apparatus having an actuator, a driver cooperatively engaged with the actuator such that the driver is caused to rotate by rotary movement created by the actuator, and a pair of opposed jaw members either disposed through the driver and movable to open and closed positions in a reciprocating linear motion along the driver or coupled to the driver and movable to open and closed positions as the driver moves in a reciprocating motion.
