A compressor includes a rotor having an outer compression surface and a plurality of inner heat exchange surfaces. A coolant supply manifold fluidly connects with a coolant inlet in a first axial end of the rotor, and delivers coolant fluid by way of conduits having an axial distribution in the rotor so as to deliver coolant fluid to the heat exchange surfaces. The coolant may be a refrigerant that undergoes a phase change within the rotor.

The present disclosure provides a system including an oil flooded compressor operable for compressing a working fluid. A dehumidifier is positioned upstream of the compressor to reduce the humidity of working fluid entering the compressor and to cool oil while regenerating the dehumidifier. A heat exchanger positioned upstream of the compressor includes passageways for oil and compressible working fluid to be transported in a heat transfer relationship therethrough such that the temperature of the oil is reduced within the heat exchanger. A control system including an electronic controller is operable for controlling an inlet temperature of the oil entering the compressor, controlling an inlet temperature and humidity of working fluid entering the compressor and a discharge temperature of the working fluid exiting the compressor.

The present disclosure is directed to an instrumentation fitting with a liquid seal to prevent fluid leakage therefrom. The instrumentation fitting includes a connector configured to connect to an apparatus having a pressurized region with fluid therein. A sealing grommet is positionable within the connector and an extension tube is engageable with the sealing grommet within the connector. The extension tube is configured to extend to a height H above the pressurized region and fill with liquid to a height level h to provide a hydraulic head sufficient to equalize the pressure within the pressurized region.

An impact tool work attachment (14) is configured to receive a handle assembly (12) along a first axis (42). A prime mover (16) is positioned in the handle assembly (12) and has an output shaft (40) rotatable about the first axis (42). The work attachment (14) comprises an output drive, a gear assembly (58) and an impact mechanism (60). The output drive is supported in the work attachment (14) for rotation about an output axis non-parallel to the first axis (42). The gear assembly (58) is positioned within the work attachment (14). The gear assembly (58) has at least one spur gear and is operable to transfer torque from the prime mover (16) about the first axis (42) to the output drive about the output axis. The impact mechanism (60) is positioned within the work attachment (14). The impact mechanism (60) has a hammer (100) and an anvil (110). The hammer (100) is configured to be rotated by the prime mover (16) and is operable to periodically deliver an impact load to the anvil (110). The output drive is rotated about the output axis under the influence of the impact load delivered to the anvil (110).

The application is directed to a compressor having a housing with a fluid compression region to rotatably support a compressor rotor. The housing includes an inner wall formed as a thin wall positioned about the compression region and an outer wall spaced radially outward of the inner wall. A cooling chamber is formed in a space between the inner and outer walls. A rib formed on the inner wall projects into the cooling chamber to provide structural support and prevent thermal deformation of the thin inner wall during compressor operation.

In at least one illustrative embodiment, a diaphragm pump may comprise a sleeve formed to include (i) a bore extending along a longitudinal axis and (ii) a sleeve port that opens to the bore, and a spool supported in the bore of the sleeve and formed to include a spool port, the spool being configured to move with a diaphragm during at least a portion of a stroke of the diaphragm such that the spool slides relative to the sleeve and, when the diaphragm reaches a turndown position that is between first and second end-of-stroke positions, the spool port aligns with the sleeve port to cause a pilot signal to be supplied to a cut-off valve. At least one of the sleeve and the spool may be rotatable about the longitudinal axis to adjust a location of the turndown position relative to the first and second end-of-stroke positions.
