  • Patent number: 10815996
    Abstract: The present invention relates primarily to a method for controlling the rotational rate of a compressor, which controls, in particular, the rotational rate of a rotating compression element of the compressor. The invention furthermore relates to a compressor, e.g. a compressor for generating pressurized air. The compressor is to be operated at a rotational rate, when in operation, with a mean value that is at least as high as a minimum mean value, in order to ensure the functionality of the compressor. According to the method, a temporally variable target rotational rate of the compressor that is necessary for obtaining a temporally variable output performance from a compressor is determined. In accordance with the invention, a lower rotational rate limit is raised if the temporal mean of the variable target rotational rate is lower than the minimal mean value for the rotational rate of the compressor.

The connection portion is partly received in a passing area formed between the housing and the motor. The housing has a suction port and a discharge port. The discharge port is located at a position farther from the partition than the suction port and the passing area. An insertion member in the passing area restricts flow of refrigerant in the housing toward the discharge port via the passing area.

  • Publication number: 20150118066
    Abstract: A method and apparatus are disclosed for selectively providing a fluid communication path between a plunger element and a contact region of an intermediate element that drives the plunger element. The fluid communication path is suitable for lubricant flow to enable a contact zone to occasionally be lubricated. The apparatus includes an elongate plunger element comprising a first end region, an intermediate element comprising a contact region arranged to selectively abut with and thereby urge a further end region of the plunger element and a spring seat member at the further end region of the plunger element. The spring seat member biases the further end region of the plunger element away from the intermediate element during a portion of a cycle of motion of the plunger element. A fluid communication path is thereby provided between an abutment surface of the further end region and the contact region.
