HIGH PRESSURE HOUSING Russian patent published in 2010 - IPC F17C1/06 

FIELD: engines and pumps.

SUBSTANCE: invention refers to load-carrying constructions operating in conditions of alternating axial loads, torque and bending moments, as well as high internal and/or external pressure. In high pressure housing containing pressure shell from polymer composite material and metal reducers having a taper part, which are connected to each other, pressure shell is two-layered, each reducer is moulded as taper part between shell layers, internal surface of moulded part of each reducer is equipped with flat thread by means of which each reducer is connected to threaded section of internal shell layer, and external surface of moulded part of each reducer represents alternating annular grooves and projections; at that, internal surface of non-moulded part of each reducer and internal surface of pressure shell have common generatrix, and end zones of moulded part of each reducer are sealed with elastic sealing elements in the form of hollow cylinder of rectangular or oval cross section.

EFFECT: reliability at simultaneous perception of alternating axial loads and external and internal pressure.
