  • Dynamic vibration control systems and methods for industrial lift trucks
    Patent number: 9403667
    Abstract: A lift truck includes systems and methods for improved vibration control. Vibration control features reduce or eliminate motion of the truck in one or more of the X-axis, Y-axis, and Z-axis. Some embodiments may include, alone or in combination with the vibration control, stability control to further stabilize the motion of the truck.

  • Combination valve for screw compressors
    Patent number: 5807081
    Abstract: Normally closed valve structure is located in a fluid path between the suction and discharge sides of a compressor. The valve structure opens upon a small pressure differential when the higher pressure is in the normal suction side which is indicative of reverse operation. Additionally, relief valve structure opens when the discharge pressure becomes excessive.

  • Condition responsive muffler for refrigerant compressors
    Patent number: 5475189
    Abstract: Pulses are sensed at the inlet and outlet of a two-chamber reflective muffler and responsive thereto the cavities are tuned to the frequency of the pulses. Specifically, chamber walls are moved to have them located at spacings corresponding, respectively, to one half and one quarter of the wavelength of the pulses.

  • Combination muffler and check valve for a screw compressor
    Patent number: 5208429
    Abstract: A weight biased check valve is located in a reflective muffler at the entrance thereof. As a result, both the check valve and muffler are located proximate to a compressor which minimizes both the package size and the volume trapped upon shutdown. The axis of the weight biased check valve is skewed whereby the weight biasing effect is reduced.

  • Oil separator
    Patent number: 5170640
    Abstract: Oil laden refrigerant is supplied tangentially into an oil separator for a primary removal of oil and then into a coalescer for a secondary removal of oil. Flow between the oil separator and coalescer is controlled by a valve so as to insure that a rapid build up of pressure takes place in the sump to insure adequate lubrication to the compressor.

  • Capacity volume ratio control for twin screw compressors
    Patent number: 5044894
    Abstract: The slide valve and the slide stop of a screw compressor are infinitely positionable over their range of movement. Movement is achieved by fluid pressure acting across an actuating piston in combination with the fluid pressure acting on the slide valve and slide stop plus a spring bias.
