Float chamber

from Wikipedia, the free encyclopedia

A float chamber is a fitting which, in combination with a float needle valve , is used to regulate the supply of liquid. The system is similar to that of a float valve , with the difference that here the level is only used as an auxiliary variable for control.

As a rule, the float chamber is known from its use in carburetors , but is used e.g. B. also used in older design oil heating systems.

It contains the following components or functions:

  • Float chamber as a container for the liquid to be regulated
  • Hydration
  • Control element: float needle valve
  • Measuring element: float, controls the needle valve
  • Liquid discharge (e.g. carburetor main nozzle in the nozzle assembly)

The incoming liquid is throttled by the needle valve. The opening width of the needle valve is determined by the liquid level in the float chamber, in that the float closes the needle valve when the level rises and opens it when the level falls.
