    Abstract: A manualy set electronic control for a fluid compression device includes a compressor (10) for pressurizing fluid and a controller (60) for indicating operating parameters and functions of the compressor. The controller graphically displays the parameters and functions, sets the limits of the parameters and controls the compressor (10) in response to any of the parameters reaching a preset level of the corresponding function. The controller (60) monitors which mode the compressor (10) is operating in, and changes the mode if the controller determines another mode would be more efficient. A computer (118) generates a signal. Communication systems are included whereby the signal from the computer (118) is communicated to the controller (60).

    Abstract: A compressor protection method and system capable of continuously establishing compressor discharge temperature set points based on actual in-service conditions and detecting damaged compressor valves for a given cylinder at each stage of compression. The method and system utilize sensors configured to monitor process property parameters (e.g. temperature and pressure) at the inlet section and outlet section of a compressor stage. The sensors generate monitored signals corresponding to the process property parameters. The method and system utilize a controller configured to receive and process these monitored signals. The controller executes a control logic that uses the monitored signals to either estimate or calculate compressor valve pressure losses for determining internal cylinder pressures, which are used to calculate compressor discharge temperature set points. The control logic compares the monitored temperature to the temperature set points and may generate a warning or normal operation signals based on results of the comparison.

    Abstract: A controlled, variable displacement, wobble plate compressor includes a pivotable wobble plate driven through an improved drive and support linkage including a universal joint and having its pivot point offset from the axis of the drive shaft so that at the "no stroke" position the pistons are all disposed at their top-dead-center positions. The capacity of the compressor is controlled by an improved system for varying the position of the wobble plate.

    Abstract: PURPOSE: To improve controlling and responding properties by providing a control valve, increasing and decreasing the inner pressure of a crank chamber to increase and decrease the slant angle of the oscillating board by communicating the crank chamber with a suction chamber and a delivery chamber selectively in response to signals indicating predetermined parameters.
    CONSTITUTION: An elastic means 31, energizing the oscillating board 20 into the direction to decrease the slant angle thereof, and a control valve mechanism 38, connecting the crank chamber 42 to a suction pressure space 33 and a delivery pressure space 34 through first port 39
    1 and the second port 39
    2 in response to the signals indicating predetermined parameters to control the slant angle of the oscillating board 20 with good responding property by changing the inner pressure of the crank chamber 42 rapidly, are provided in the compressor. According to this method, a clutch is unnecessitated in the connection with an engine and high delivery pressure is introduced directly into the crank chamber 42 when the amount of delivery is to be decreased, therefore, very quick responding property may be obtained.
