摘要： 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.

摘要： 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.

摘要： A thermally protected heater element is located in an oil sump such that it is normally located beneath the surface of the oil whereby the oil is heated and acts as a heat sink relative to the heater element. If the oil level drops below the heater element, the thermal protection disables the heater element and the compressor whereby the location of the heater element defines the nominal minimum oil level.

摘要： A vehicle includes a vehicle frame, a vertical mast coupled to the vehicle frame, and a carriage movably mounted to the mast for ascending and descending along the mast. At least one hydraulic cylinder moves the carriage along the mast, a hydraulic pump pumps hydraulic fluid into the hydraulic cylinder, and a flow valve controls the flow of hydraulic fluid between the hydraulic pump and the hydraulic cylinder. A sensor senses an actual descent speed of the carriage and a controller controls the flow valve to allow descent of the carriage at a requested descent speed. The controller controls the flow valve to limit descent of the carriage to a unsolicited descent speed limit if a difference between the actual descent speed and the requested descent speed exceeds a threshold value.

摘要： A pressure responsive oil flow regulating supply valve assembly includes an oil supply input; an oil supply output; an oil flow path defined between the input and output. A valving mechanism located in the oil flow path includes a device for restricting oil flow at a first level in response to normal pressure and for restricting oil flow at a second level in response to high pressure conditions. In addition, other levels of restriction may be provided for other pressure conditions.
