    摘要： A variable capacity hydraulic machine has a rotating group located within a casing and a control housing secured to the casing to extend across and seal an opening in the casing. The control housing accommodates a control circuit and a pair of sensors to sense change in parameters associated with the rotating group. One of the sensors is positioned adjacent the barrel on the rotating group to sense rotational speed and the other senses displacement of the swashplate. The control housing accommodates a control valve and accumulator to supply fluid to the control valve.

    摘要： A method for detection of a leak in a fluid affected component of a piston machine includes obtaining a vibration signal from a vibration sensor disposed proximate to at least one valve block of the piston machine. The vibration signal includes vibration generated by valves in the valve block. The method further includes presenting the obtained vibration signal for analysis by at least one of a human or a computer, analyzing the obtained vibration signal with respect to revealing a malfunction related to a fluid affected component of the piston machine, and selecting the obtained vibration signal emitted from the valve block during the closed periods of the valves for presentation.

    摘要： A variable frequency control module includes a temperature detecting unit outputting a detecting signal corresponding to ambient temperature detected thereby, an operating unit operable so as to output an input signal corresponding to a target temperature, and a processing unit receiving the detecting signal and the input signal from the temperature detecting unit and the operating unit., and outputting a control signal corresponding to a difference between the ambient temperature and the target temperature based on the detecting signal and the input signal. An encoding unit receives the control signal from the processing unit, encodes the control signal into an encoded signal, and outputs the encoded signal to a frequency converting unit that outputs a driving signal having a frequency corresponding to the encoded signal to an AC compressor so that an AC compressor is operated at a rotary speed based on the driving signal.
