Abstract
A lubrication system is provided for supplying lubricant to an air compressor. The air compressor is driven by a drive system. The lubrication system includes a reservoir configured to support lubricant and configured to receive pressurized air from the air compressor, the separator reservoir configured to separate lubricant from the air received from the air compressor; and a motor operably coupled to the drive system and configured to receive pressurized lubricant. The motor is configured to transmit power to the drive system in at least one operating condition.
Claims24
An industrial machine comprising:
- a working tool;
- an air supply system for supplying pressurized air for operating the tool, the air supply system including an air compressor supplying pressurized air at an output;
- a drive system for driving at least the air compressor;
- and
- a lubrication system for supplying lubricant to the air compressor, the lubrication system including:
- a reservoir configured to support lubricant, the reservoir configured to receive pressurized air from the air compressor;
- and
- a motor operably coupled to the drive system and configured to receive pressurized lubricant, flow of lubricant driving the motor to transmit power to the drive system in at least one operating condition.
A lubrication system for supplying lubricant to an air compressor, the air compressor driven by a drive system, the lubrication system comprising:
- a separator reservoir configured to support lubricant and configured to receive pressurized air from the air compressor, the separator reservoir configured to separate lubricant from the air received from the air compressor;
- and
- a motor operably coupled to the drive system and configured to receive pressurized lubricant, the motor being configured to transmit power to the drive system in at least one operating condition.
A lubrication system for supplying lubricant to an air compressor for a drill, the air compressor driven by a drive system, the lubrication system comprising:
- a separator reservoir configured to support lubricant and configured to receive pressurized air from the air compressor, the separator reservoir configured to separate lubricant from the air received from the air compressor;
- a cooler configured to reduce a temperature of the lubricant being driven to the air compressor;
- and
- a motor operably coupled to the drive system and configured to receive pressurized lubricant, the motor being configured to transmit power to the drive system in a first mode in which pressure of the air in the reservoir is sufficient to drive the lubricant from the reservoir through the motor, the motor being configured to be driven by the drive system to drive the lubricant in a second mode in which pressure of the air in the reservoir is insufficient to drive the lubricant from the reservoir and through the motor.
