  • Patent number: 11396873
    Abstract: Embodiments of the present disclosure provide a scroll compressor. The scroll compressor includes: a fixed scroll having an end plate and a fixed scroll wrap extending from the end plate; an orbiting scroll having an orbiting scroll wrap, the orbiting scroll wrap being engaged with the fixed scroll wrap to form a plurality of compression chambers for compressing a medium; a channel formed in the end plate of the fixed scroll, the channel leading to one compression chamber of the plurality of compression chambers; and a valve provided on the end plate of the fixed scroll, and configured to open when a pressure in the one compression chamber is higher than a predetermined pressure threshold so as to allow the medium in the one compression chamber to flow out of the one compression chamber through the channel. The scroll compressor according to the embodiments of the present disclosure, for example, can improve the performance of the scroll compressor.

  • Patent number: 9518582
    Abstract: A motor spacer for a variable-speed compressor positions and supports a stator of a motor in a cylindrical section of a compressor shell. The spacer includes a ring member and a plurality of support blocks. The ring member is coaxially mounted around the stator by a clamping force. Each support block protrudes radially and outwardly from the ring member and has a hollow frame structure with a closed enclosure. Each support block has a support surface in contact with the shell. Each support surface is located on a side of an imaginary ring cylinder having a common axis with the ring member. The plurality of the support blocks are adapted to mount the motor spacer onto an inner side of the shell by a clamping force.

  • Patent number: 7722251
    Abstract: A device for inspecting contraband in an aviation cargo container includes: a turntable and a scanning system, the scanning system including a radiation source; a detector; a radiation source mounting structure; and a detector mounting structure for mounting the detector. Each of said radiation source mounting structure and said detector mounting structure includes at least one column assembly. The radiation source and the detector are mounted on the column assembly and allowed to synchronously ascend and descend along said column assembly. By combining different movement modes of the turntable and the scanning system, the device of the present invention can scan the object in various scanning modes. The device is stable in structure, convenient in installation, and occupies a small space. The device can inspect aviation containers over two meters long and/or over two meters wide and achieve a relatively high passing rate of the objects.

  • Patent number: 7702070
    Abstract: A device for inspecting contraband in an aviation cargo containers includes: a turntable located at an object inspecting position and configured to carry the object to be inspected and bring the object into rotation; an object conveying system; a scanning system including a radiation source and a detector which can synchronously move in the vertical direction; a turntable drive/control system which drives and controls rotation of said turntable so that the turntable can continuously rotate about its rotation axis or rotate to any predetermined angular position; a scanning drive/control system which drives and controls the radiation source and the detector into synchronous movement in the vertical direction so that the radiation source and the detector can continuously move in the vertical direction or move to any predetermined vertical position. The device of the present invention can scan the object and form images in various scanning modes to meet different needs.

  • Publication number: 20080165934
    Abstract: A composite rotary-delivery worktable for use in an air container detection system, which is attached to a scanning passage of an air container diction system, said composite rotary-delivery worktable comprising a delivery assembly for carrying and delivering said air container; and a rotary assembly rotatable with a rotation axis, wherein said delivery assembly is attached to said rotary assembly such that said delivery assembly is rotatable with said rotary assembly when said rotary assembly rotates. The composite rotary-delivery worktable of this invention enables large-scale air containers to not only pass the scanning passage but also rotate freely within the scanning passage. This makes it possible to keep the scanning system fixed and stationary, thereby increasing the working reliability of the scanning system and reducing the design difficulty and complexity of the scanning system.
