Abstract
Disclosed are pin swivels. In at least one example embodiment, a pin swivel includes a housing attachable to a mechanical assembly and a spool rotationally supported by the housing. In at least one example embodiment the housing includes at least one port configured to connect to at least one hose to receive at least one fluid from the at least one hose, and at least one channel configured to transfer the at least one fluid to at least one fluid transfer area. In at least one example the spool has at least one channel in fluid communication with the at least one fluid transfer area of the housing to receive the at least one fluid from the at least one fluid transfer area, and at least one port configured to receive the at least one fluid from the at least one channel of the spool.
Claims8
A pin swivel comprising:
- a housing attachable to a mechanical assembly, the housing including at least one port configured to connect to at least one hose to receive at least one fluid from the at least one hose, and at least one channel configured to transfer the at least one fluid to at least one fluid transfer area;
- and
- a spool rotationally supported by the housing, the spool having at least one channel in fluid communication with the at least one fluid transfer area of the housing to receive the at least one fluid from the at least one fluid transfer area, and at least one port configured to receive the at least one fluid from the at least one channel of the spool, wherein at least one cross section of the at least one channel of the spool transitions from a circular shape to an oval shape and then to a kidney bean shape to reduce fluid turbulence and heat buildup.
