Abstract: Disclosed is a sliding shoe for a rotatable swash-plate type refrigerant gas compressor. This shoe is slidably connected between a rotatable swash-plate and a ball rotatably engaged with a piston. One of the major surfaces of the shoe slidably contacts a sliding surface of the swash-plate. A sliding surface of the shoe facing the swash-plate is formed with a flat plane at its center portion and chamfered surface at the remaining portion of the sliding surface. At least the sliding plane of the shoe is coated with a lead alloy. According to the present invention, even if the swash-plate type compressor has no lubrication, abrasion and seizing of the shoe can be reduced to a great extent.

Abstract: An improved method and apparatus for jetting auxiliary fluid to a fluid and filling guide passage formed on a sley in a jet loom wherein a plurality auxiliary nozzles are vertically disposed at predetermined intervals to confront the opening of the guide passage, the entire region in the direction perpendicular to the longitudinal direction of the opening of the guide passage is covered by the auxiliary fluid jetted from the opening of the respective nozzles.
