'I'hiseliminates the pulsat- 56 ing operation in the condenser and totally eliminates any pulsating effect in the total volume of steam exposed to vacuum. I am therefore able to eliminate entrainment losses which are normally present in condensers having a series of flat plates or baflies. Such a condenser is also less expensive to manufacture in that it has fewer parts than in the prior known structures and it has no material maintenance problems.

While I have shown a' preferred form of embodiment of my condenser it will be understood that modifications may be made therein and I therefore desire a broad interpretation of my invention within the scope and spirit of the description thereof and of the claims appended hereinafter.

I claim:

1. A counter-current vapor condenser 01' the class described comprising a primary condensing chamber having an inlet for vapors, a secondary condenser chamber, a water receiving chamber and an uncondensible vapor collecting chamber, a weir in said water receiving chamber to form a closed curtain of water between the uncondensible vapor collecting chamber and the secondary condensing chamber, an umbrella shaped baiile below said closed curtain of water to deflect the curta'n of water against the sides of the condenser to close the secondary condensing chamber, a deflector portion on said condenser below the secondary condensing chamber to form a second curtain of water flowing through the primary condensing chamber and being spaced from the sides thereof, a'transverse member in alignment with the vapor inlet in the path of flow of the second curtain of water to form openings on opposite sides of the curtain of water whereby vapors may enter within the curtain of water without any substantial deflection of the water curtain, and means to discharge uncondensed vapors and water at opposite ends of the condenser.

2. A steam condenser of the class described having a condensing chamber having an inlet into which steam is admitted, a water chamber above the condensing chamber, a weir in said water chamber and an umbrella shaped deflector below said weir, said deflector and weir forming a closed curtain of water separating the condensing chamber from the water chamber, deflector means near the top of the condenser chamber to form a substantially conical curtain of water in the condensing chamber, and means to ininterrupt the water flow from said deflector to iorm openings in said water curtain adjacent the steam entrance whereby the entering steam will pass into and around the water curtain and the curtain will remain in pressure balance.

3. A steam condenser having a main steam condensing chamber with a steam inlet therein, a secondary steam condensing chamber, and an air collection chamber, said air collection chamber having a water inlet and an air outlet, means to form a closed curtain of water between said air collection chamber and said secondary steam condensing chamber, means to form a second closed curtain of water separating said secondary steam condensing chamber from said main condensing chamber, means to form a conical flow of water through said main condensing chamber, and means to form diametrically opposite openings in said conical flow of water in alignment with said steam inlet whereby steam may surround said water flow without substantially deflecting it.
