Abstract
A compression generator uses a plurality of jackbolts threadedly engaged at a spaced apart relation about a bolt circle in a main core element. The main core element is releasable interlocked by threads, bayonet connection or other form of fasting system with the mounting element forming a fixed part of the mechanical connection. The jackbolts torqued to generate a pushing force in an axial direction for compressing a moveable part of the mechanical connection against a compression seat for forming a mechanical connection between juxtaposition fixed and moveable parts.
Claims3
A compression generator assembly comprising:
- a valve manifold;
- a compression generator comprising:
- a fixed part comprising a collar;
- a moveable part comprising a valve;
- a carrier comprising a round-shaped access plug and including threads on the external peripheral edge of said carrier for retained support by said fixed part and in a confronting relation to said moveable part, and
- a plurality of jackbolts each received in one of a plurality of holes at spaced-apart locations about an outer peripheral part of said carrier;
- wherein said collar is mounted against said valve manifold and which collar is releasably joined by threaded fasteners to said valve manifold, said collar having a central opening containing screw threads to receive the threads of said carrier;
- and
- wherein said fixed part and said moveable part form a mechanical connection therebetween by transmitting a pushing force against a surface of said moveable part, and said jackbolts receive torque to generate said pushing force.
