An improved seal for use in fluid systems such as a water jet system includes an outer seal point that is very close to an inner seal point. By spacing these two seal points very close together, the force on the seal is greatly reduced compared to the prior art. In the disclosed embodiment, the outer seal point is on an angled forward face of the seal that abuts a back-up ring angled face. The inner seal point is between the seal and an internal shaft which rotates relative to a housing.

Rotating fluid jet with improved rotary seal

A valve assembly for use with a high pressure fluid gun includes a valve seat connected to a valve sleeve by a spring. The valve seat and the valve sleeve are crimped around opposing ends of the spring. A valve pin is secured to the valve sleeve, the spring allowing for the movement of the valve pin when a trigger mechanism is actuated. When installed, the valve pin is received and guided by a bore in the body of the fluid gun. When the valve pin is actuated by a trigger mechanism, a seat end of the valve pin sealingly engages an angled seat of the valve seat to direct the flow of fluid through a high pressure outlet.
