A quick-fill apparatus for use with a valve assembly, and related methods of filling a pressure vessel, are disclosed. A valve assembly may be affixed to a pressure vessel, and may include a receptacle, a fill valve and an overfill valve. Preferred examples of the apparatus comprise a body, a valve trigger pin, a vent trigger pin and a handle. A valve engagement end of the body may be releasably securable within the receptacle. At that point, moving the handle to the on position causes the valve trigger pin to force the fill valve to an open configuration, and causes the vent trigger pin to force the overfill valve to a fluid venting configuration. A rigid fill tube may be in fluid supplying communication with a fuel supply port of the body. The fill tube and the handle may be elongated and extend in a shared direction.

Quick-fill apparatus, system and method for fuel valves

A safety relief fill valve adapted to being an interface for filling and relieving excess pressure from a closed fluid system. An insert shell retains a piston member for movement between fluid input and fluid holding configurations, the piston member being resiliently biased toward fluid holding configuration. When in fluid holding configuration, the piston member sealingly engages an inlet bore of the insert shell. When in fluid input configuration, the piston member allows fluid flow through the inlet bore. A housing receives the insert shell, thereby limiting relative axial movement and forming a cavity between a portion of the housing the insert shell. This cavity provides mechanical guidance and a flow channel for an overpressure relief system having fluid retaining and fluid relief configurations, the overpressure relief system being elastically biased toward fluid retaining configuration. The elastic bias is overcome responsive to excess pressure within the closed fluid system.

Safety relief fill valve assembly

A low-profile burst disk assembly for safely venting excess pressure from a pressurized fluid system by way of a tortuous fluid flow path. A burst disk plug includes a male thread and is thereby adapted to thread into the body of a pressurizable chamber. The burst disk plug further includes a fluid receiving port placed in fluid communication between the burst disk and one or more bleed channels open to ambient pressure. The one or more bleed channels generally run axially through the burst disk plug, either intersecting or bypassing the male thread. Embodiments with a plurality of bleed channels generally include a distribution manifold positioned in fluid communication between the fluid receiving port and the one or more bleed channels to ensure an even distribution of venting pressure among the bleed channels. A flange surface further deflects pressurized fluid as it escapes from the bleed channels toward the ambient environment, thereby dispersing the resulting thrust in multiple directions and minimizing the effective force exerted on the body of the pressurized fluid system.
