Fueling arm
First Claim
1. A fueling arm which can be connected to a supply line, comprising a filler-neck coupling and eight pipe sections which are serially connected to each other by respective swivel joints which each have only one degree of freedom, wherein at one end of a first of said pipe sections there is arranged a first of said swivel joints which can pivotally couple said first pipe section to the supply line, wherein an axis of rotation of said first swivel joint and axes of rotation of second and third said swivel joints which successively follow said first swivel joint are disposed in planes which are parallel to one another, wherein said third swivel joint is movable and is guided by guide means for reciprocal movement parallel to a direction of movement, a second of said pipe sections being pivotally coupled to said first pipe section by said second swivel joint and to a third of said pipe sections by said third swivel joint, wherein said fueling arm includes a headpiece which includes said filler-neck coupling and each of said pipe sections other than said first, second and third pipe sections, wherein an end of said headpiece remote from said filler-neck coupling is connected by a fourth of said swivel joints to said third pipe section, wherein said headpiece is movable to a position in which three of said swivel joints thereof have axes of rotation which are parallel to one another and are perpendicular to the axes of the other two swivel joints thereof, wherein said axes of rotation of said first, second and third swivel joints are horizontal, and wherein said guide means includes a guide rail and includes one of said third swivel joint and said third pipe section being movably supported by said guide rail.

Abstract
A fueling arm without the need for any hoses which can be connected to a supply line, particularly for tank cars and aircraft fueling, is disposed in a chute. To assure effortless handling and reduce fueling time, the fueling arm includes at least eight pipe sections which are connected by swivel joints, wherein at one end of a first pipe section there is a first of the swivel joints. The axes of rotation of the first and of successive second and third swivel joints are parallel. The first swivel joint can be connected to a supply line and the third swivel joint is guided in a direction of movement thereof. A headpiece with a filler-neck coupling thereon is connected by a fourth swivel joint to a second of the pipe sections which is also connected to the third swivel joint. The headpiece has a line which includes five of the pipe sections and, of the five swivel joints connected to the line, three have parallel axes of rotation and the remaining two have axes perpendicular to the axes of the other three.

6. A fueling system, comprising:
- a stationary supply line;
first, second and third pipe sections;
first, second and third swivel joints which have parallel, horizontal axes of rotation, said first swivel joint pivotally coupling said supply line to one end of said first pipe section, said second swivel joint pivotally coupling the opposite end of said first pipe section to one end of said second pipe section, and said third swivel joint pivotally coupling the opposite end of said second pipe section to one end of said third pipe section;
a fourth swivel joint provided at the opposite end of said third pipe section and having a vertical axis of rotation; and
a headpiece line having one end coupled to said third pipe section by said fourth swivel joint and having at its opposite end a filler-neck coupling, said headpiece line including a plurality of further pipe sections connected in series by respective further swivel joints, successive said further swivel joints in a direction of fluid flow having perpendicular axes of rotation; and
guide means supporting said third pipe section for approximately vertical movement between raised and lowered positions in which said third swivel joint is respectively spaced above and in the region of said first swivel joint, said guide means including an elongate vertical guide rail and means supporting said third pipe section on said guide rail for movement lengthwise thereof. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
