Embodiment Construction

[0010] The system uses a Z-type rotary switch 10 constructed of aluminum. The Z-type rotary switch 10 is capable of rotating four components (12, 16, 22 and 24) in three independent axes. Rotary switches allow media flow and are sealed from the outside environment. A Z-type rotary switch 10 is used between the hose 30 and the applicator tool 32 and allows them to move freely without hose twisting causing additional forces to be dealt with by the operator.

[0011] The Z-type rotary switch 10 includes a female coupling 12 designed to be attached to a hose 30 (or applicator 32 ) and in turn to an inlet post 14 , which is rotatably located in a sealed housing 16 . Seals 18 and 20 seal and allow rotation between column 14 and seal housing 16 . Similarly, the seal housing 16 contains a seal 34 that allows the seal housing 16 to rotate relative to the center post 22 . Outlet coupling 24 is rotatably attached to center post 22 with seal 28 and held in place by retaining ring 26 . ...

Abstract

Z-swivel 10 is comprised of a female coupling 12 designed to attach to a hose 30 (or application device 32) and in turn is attached to an inlet stud 14 which is rotatably located in seal housing 16. Seals 18 and 20 seal and allow rotation between stud 14 and seal housing 16. Similarly, seal housing 16 contains seals 34 which allow rotation of seal housing 16 relative to center stud 22. Outlet coupling 24 is rotatably attached to center stud 22 with seals 28 and retained in place by retaining ring 26. Pipe plug 36 seals the end of center stud 22. Passages 38, 42, 40, 46 and 44 connect in that order to allow flow of fluid including thick and viscous fluids such as drywall mud through the swivel.

Description

technical field [0001] This application claims the benefit of US Application Serial No. 61 / 315,291, filed March 18, 2010, the contents of which are incorporated herein by reference. Background technique [0002] Z-type rotary switches are generally known to allow hose twisting. Contents of the invention [0003] One of the objects of the present invention is to develop a Z-type rotary switch which is lightweight, high flow, high pressure resistant and can be used in drywall joint finishing. [0004] The system uses Z-style rotary switches constructed of aluminum. The Z-style rotary switch is capable of rotating four components in three independent axes. Rotary switches allow media flow and are sealed from the outside environment. A Z-type rotary switch is used between the hose and applicator tool and allows them to move freely without causing twisting of the hose which causes extra force to be dealt with by the operator. [0005] A Z-type rotary switch is used to elimi...
