Abstract
The fluid pressure-responsive unit of the invention defines a chamber formed of a base plate, a top plate and a heat-exchange bellows sidewall joining the two plates. Relative movement of the plates is controlled by springs and guiding cylinders within the chamber. The base plate incorporates a fluid intake aperture for admitting fluid into the chamber and the latter further contains an overflow assembly including a looped resilient pipe of which one end is connected to the top plate so as to receive fluid overflowing from the chamber. The other end can be connected to another pipe introduced into the chamber by the intake aperture to lead fluid out of the chamber.
Claims14
A fluid pressure-responsive unit comprising:
- a base plate;
- a top plate;
- a bellows sidewall made of heat-exchanging material and fluid tightly connected at base and top ends, respectively to said base and top plates, said base plate, top plate and bellows sidewall defining a fluid chamber;
- resilient return means interconnecting said plates within the fluid chamber so as to allow movement of said plates relative to one another, whereby the fluid chamber may expand and contract responsive to fluid pressure fluctuations;
- fluid intake aperture formed in said base plate for admitting fluid into the fluid chamber, said aperture being formed so as to allow operative connection of the unit to a return overflow conduit;
- a fluid overflow conduit fixedly located in the fluid chamber, said conduit having a first end provided with a first connecting means for fixing the first end inside the fluid chamber, the first end being fixed in a predetermined position for receiving fluid overflowing from the fluid chamber, and said conduit further having a second end provided with a second connecting means for connecting the second end to the return overflow conduit operatively connected to the fluid chamber so as to lead overflowing fluid out of the fluid chamber;
- and
- guiding and stopping means located in the fluid chamber and interconnecting said plates, for guiding the movement of said plates relative to one another, and for limiting expansion of the fluid chamber when a distance between said plates reaches a predetermined length.

- and
- guiding and stopping means located in said fluid chamber and interconnecting the plates, for guiding the movement of the plates relative to one another, and for limiting expansion of said fluid chamber when a distance between the plates reaches a predetermined length.
