  • the parts are few in number and in the main are inexpensive easily formed sheet metal stamplngs ⁇ which can be put together in a simple fashion and kept in good working order. Furthermore the parts are designed to be positive in action without the need for extreme accuracy in manufacture, thus promoting economic large quantity production.

  • the C-shaped retainer 38 is formed as shownrin Figure 5 softhat spaces between its straight portions and the cylinder 32 provide breathing passageways around the valve for communicating the system with the overflow vent
  • the system normally is in free communication with atmosphere and avoids compression of vapors within the system and a bulging pressure on the radiator core, as the body of liquid warms up.
  • the moving body of liquid will raisev the valve to its seat thereby resisting expulsion of the liquid and upon the subsequent recession of the pressure pulsation, the valve immediately opens to relieve any suction effect and avoid bursting strains on the hose connections and fragile core assembly.
  • the relation of the retainer head 26 and the inturned flange 28 of the valve assembly is such that if the cap is to be removed, its backward rotation and concurrent outward movement toward the position wherein the fingers I8 engage with the safety stops 20, will cause the head 26 to engage with the ange 28 and lift the gasket 30 off the seat I3 for free communication of the system through the overflow. pipe.
  • internal pressure is relieved prior to complete removal of the cap and the person removing the cap after noting that the internal pressure has been relieved may then depress the cap slightly moving the fingers I8 inwardly to clear the stop 20 and complete the detachment of the cap from the spout.
