Abstract

The equipment housing is connected to a vacuum source, and has its lower part divided into a number of compartments with upper and lower openings connecting them to the housing and to atmosphere, the upper opening being shut by a valve. The sole factor causing opening or shutting of the valve is the pressure difference between the compartment and the housing and, when shut, the valve seals the compartment as tightly as possible. Preferably the valve is in the form of a disc secured to a rod brought out of the compartment via the top opening, a sealing ring being fitted on top of the disc edge. On the valve rod can be provided a stop to restrict its extent of downwards movement.
