Adjustable and constant volume flotation device for e.g. submarine plunger, has expansion valve and discharger regulator for assuring supply and purging of gas towards internal gas volume of float

摘要

#CMT# #/CMT# The device has a float (11) with an elastic and flexible membrane (23) filled with gas. Pressure of the float is regulated according to immersion depth. The membrane defines a predetermined internal gas volume (29) based on the elasticity of the membrane and internal pressure of the volume with respect to external ambient pressure (33). An expansion valve and discharger regulator (20) assures the supply and the purging of the gas towards the volume of the float. #CMT#USE : #/CMT# Adjustable and constant volume flotation device for a submersible entity e.g. submarine plunger, being immersed at various depths. #CMT#ADVANTAGE : #/CMT# The configuration of the device allows to automatically retain a constant volume to a value chosen by the operator such as a plunger, regardless of the immersion of the operator. The utilization of the float allows the plunger to easily change the position, and provides a hydrodynamic form regardless of its inflation volume and the design of the regulator, thus reducing the size of purging valves with respect to buoy at actual constant volume. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a plunger equipping an adjustable and constant volume flotation device. 11 : Float 19 : Submarine plunger 20 : Expansion valve and discharger regulator 23 : Elastic and flexible membrane 29 : Predetermined internal gas volume 33 : External ambient pressure.
