摘要： An ejector joint structure includes first and second connection members and an ejector. The first connection member has a head portion, a body portion, and a defined-through first channel. The first channel has a stepped portion and forms a thick section and a thin section. The body portion has a through-hole communicating with the thin section. The ejector is movably threaded in the first channel via an abutting rod. The abutting rod has a flange corresponding to the thick section and selectively abutted against the stepped portion to shield the first channel. The second connection member has a sleeve to enclose an outer periphery of the first connection member, and the second connection member is rotatable relative to the first connection member. The sleeve has a second channel communicating with the hollowed space. A sealing member is assembled between the sleeve and the body portion to seal the hollowed space.

摘要： The present disclosure relates to apparatuses and methods for multi-phase vacuum-assisted recovery of refrigerant from a vehicle. One apparatus for multi-phase vacuum-assisted recovery of refrigerant from a vehicle includes a compressor that removes refrigerant from the vehicle during a first phase and a second phase of a recovery process. The apparatus also includes one or more pressure sensitive devices that are each configured to measure a first pressure and/or a second pressure in the apparatus. Upon the first pressure being less than a first threshold pressure, a vacuum pump that is fluidly connected in series with the compressor assists the compressor in the removal of refrigerant from the vehicle during a second stage of the recovery process. Also, upon the second pressure being less than a second threshold pressure, the vacuum pump ceases assisting the compressor.

摘要： A manifold gauge set has at least one sight glass window for viewing contents of a refrigeration system or an air conditioning system being serviced. The window may be non-planar to achieve an appearance that varies with the presence or absence of liquid. Such a non-planar window may be in the form of a dome, prism, or a fresnel lens. The gauge set may have a second light transmissive window to allow light to illuminate system contents being viewed. A light source may be provided to illuminate system contents being viewed. The light source may provide light through the same window that is used for viewing contents. A diffuser may be provided with a second window to achieve an illuminated background for viewing system contents. Similar configurations may be used in standalone sight glasses, vacuum pumps, and recovery machines.
