Twist lock assembly

A twist lock assembly for connecting an air supplying conduit to an air receiving engine component in a vehicle, comprising:

• an air receiving engine component having a first conduit with an air inlet opening;
• a first annular flange attached to said air receiving conduit and surrounding said opening, said first flange having an alignment slot and at least one locking slot formed therein;
• a second conduit having an open end;
• a second annular flange attached to said open end of said second conduit and having a radially inwardly extending alignment tab formed thereon;
• and
• a locking ring rotatably mounted on said second flange and having at least one radially inwardly extending locking tab formed thereon,
• whereby when said first and second flanges are abutting and concentric and said alignment tab engages said alignment slot and said at least one locking tab is aligned with said at least one locking slot, rotation of said locking ring relative to said second flange draws said first and second flanges into airtight engagement and locks said open end of said second conduit to said inlet opening of said first conduit of said engine component.

A twist lock assembly for connecting an air supplying conduit to an air receiving conduit, comprising:

• an air receiving conduit with an air inlet opening and an annular radially outwardly extending first flange at said inlet opening, said first flange having an alignment slot and a plurality of locking slots formed therein and a first sealing surface formed thereon;
• a second conduit having an open end and an annular radially outwardly extending second flange at said open end, said second flange having a radially inwardly extending alignment tab and a second sealing surface formed thereon;
• and
• a locking ring rotatably mounted on said second flange and having a plurality of locking tabs formed thereon,
• whereby when said alignment tab is engaged with said alignment slot and each of said locking tabs is engaged with a corresponding one of said locking slots by rotation of said locking ring in an engaging direction, said first and second sealing surfaces are held in airtight engagement.
