Abstract: The non-axial force exerted on a pneumatic tool by a non-axial air supply is balanced to allow for uniformly radially distributed compliance forces on the tool. An annular air ring is disposed around the pneumatic tool, covering an air inlet port. Air is supplied by any route to a first air passage that supplies the air to the interior of the annular air ring, exerting a force on the annular air ring. Air flows in the annular space of the air ring, entering the tool air inlet port to drive the pneumatic tool. One or more second air passages are connected to the annular air ring in an even radial distribution. Each second air passage is connected to the air source, or terminates in an air blockage, creating a column of pressurized air that exerts a force on the annular air ring equal to the first air passage. The forces exerted on the air ring are thus balanced with respect to the axis of the tool.

Abstract: A scroll compressor has lubricant flow which communicates lubricant onto a motor protector when adverse conditions are present causing the motor protector to trip the motor and stop further rotation. The lubricant is returned to an oil sump through a normal return path. The normal return path outlet may be positioned above the motor protector such that lubricant will contact the motor protector when adverse conditions are present, or the outlet may be remote from the protector. When the outlet is remote from the protector, a funnel and tubing divert the oil to the motor protector under adverse conditions. Alternatively, a passage communicating with the normal return path is selectively blocked when an adverse condition is present. At that time, lubricant is forced into an alternative oil path, which is positioned above the motor protector.

Abstract: When a molding machine nozzle is separated from a nozzle touch surface of a hot runner sprue, application of external pressure on resin in a resin supply passage is stopped. At this time, back pressure of resin in the resin supply passage that is received by a seal exceeds atmospheric pressure, and thus the seal is moved to seal an opening of the resin supply passage from the inside of the resin supply passage. As a result, leakage of resin from the hot runner sprue is inhibited, and mixing of air in the resin in a runner is also inhibited.
