    • 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.

    • A check valve (10) for use in the evacuation of air from a system having primary and secondary disc (32, 34) retained in a chamber of the housing (12) and responsive to first and second forces developed by the creation of a fluid pressure differential between the fluid pressure of air in a first member and a source of vacuum to control the evacuation of air from the member by the source of vacuum. The primary disc is located on a stem (38) that extends from the secondary disc to cover a plurality of openings (42, 42') which connect the inlet port (16) to the chamber. A spring (52) holds the secondary disc against the housing. The first force which develops as a result of a pressure differential between the fluid pressure of air and vacuum moves the primary disc to allow air to be evacuated through the openings in the secondary disc. Should the fluid pressure in the air located in the first member exceed a predetermined value, the second force develops which acts on the secondary disc to allow a larger volume of air to be evacuated in a shorter time. A tang (50) on the secondary disc engages the housing to prevent the development of vibrations therein when air is evacuated as a result or movement by the secondary disc. When the fluid pressure of the air is reduced to a predetermined fluid pressure, a spring moves the secondary disc into engagement with the housing and the evacuation of air is again through the openings in the secondary disc as controlled by the first disc.

    • A fluid fuse is quickly operable to shut off fluid flow upon rupture or other failure of fluid conducting line or other structural member downstream of the fuse. The fuse is actuated during decompression fluid flow resulting from decompression of fluid and elastic contraction of structural components downstream of the fluid fuse. During decompression fluid flow, a valve member (V) is moved from an open position to a closed position by two forces generated by a pressure differential caused by sudden decompression of the fluid and developed across two variable, sharp edge, viscosity insensitive orifices (36, 38), positioned in series and separated by a flow cut-off and sealing surface (26). The closing force, generated by the pressure differential of the upstream orifice (36) is dominant and increases with the displacement of the closing member (V) in a predetermined manner, permitting the use of a high preload and high rate opposing spring (23), at relatively low pressure differentials. The sealing surface (26) of the fuse is provided with limited freedom of alignment to permit tight sealing. The fuse assembly includes a manually adjustable bypass arrangement (40) and a pressure peak attenuating control (59).
