Abstract

Claims (25)

1 . 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.

2 . The pin swivel of claim 1 , wherein

the at least one port of the housing includes a first port and as second port,

the at least one channel of the housing includes a first channel and a second channel,

the at least one fluid transfer area of the housing includes a first fluid transfer area and a second fluid transfer area,

the at least one port of the spool includes a first port and a second port,

the at least one channel of the spool includes a first channel that extends from the first port of the spool through a main body of the spool and a barrel of the spool and to at least one channel that is in fluid communication with the first fluid transfer area and a second channel that extends from the second port of the spool through the main body of the spool and the barrel of the spool and to at least one channel that is in fluid communication with the second fluid transfer area.

3 . The pin swivel of claim 2 , wherein the first and second channels of the spool extend upward from the first and second ports through the body of the spool, and downwards into the barrel of the spool.

4 . The pin swivel of claim 3 , where cross sections of the first and second channels of the spool transition from a circular shape to an oval shape and then a kidney bean shape to reduce fluid turbulence and heat buildup.

5 . The pin swivel of claim 1 , further comprising:

a spool head having at least one port in fluid communication with that at least one channel of the spool.

6 . A method comprising:

attaching the pin swivel of claim 1 to the mechanical assembly, the mechanical assembly having a first arm pivotally connected to a second arm;

attaching at least one hose to the at least one port of the housing; and

attaching at least one hose to the at least one port of the spool, wherein the pin swivel is located on the mechanical assembly at a location that reduces hose bend.

7 . The method of claim 6 , further comprising:

identifying a section of the at least one hose that connects to the at least one port of the housing that bends the most;

one of modifying or replacing the at least one hose that connects to the at least one port of the housing; and

connecting the one of the modified or replaced at least one hose to the at least one port of the housing.

8 . A method of retrofitting the mechanical assembly of claim 1 comprising:

identifying a section of the at least one hose that connects to the at least one port of the housing that bends the most;

one of modifying or replacing the at least one hose that connects to the at least one port of the housing; and

connecting the one of the modified or replaced at least one hose to the at least one port of the housing.
