Abstract
Abstract A device for discharging condensation has a flat thermic actuating member filled with evaporating liquid and having a diaphragm with a centrally located closing device co-operating with the corresponding valve seat. The invention is particularly characterized in that the diaphragm is held tightly between two rigid plate-like wall parts, whereby one of the wall parts along with the diaphragm forms the receiving space for the liquid, while the other wall part supported upon the valve seat sleeve serves as a holder for the actuating member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A condensation discharging device, comprising a flat thermic actuating member adapted to be filled with a volatile liquid, and comprising a diaphragm, a closure member centrally carried by said diaphragm, a valve seat adapted to be closed by said closure member, and two opposed rigid plate-like wall members, said wall members having annular clamping members spaced from their edges for tensioning and holding said diaphragm between the two wall members, the diaphragm being soldered to the two wall members at its outer edges, and a casing having passages for the inflow and outflow of liquid and enclosing said thermic actuating member, one of said wall parts and said diaphragm enclosing a space for receiving said liquid, the other one of said wall parts having a central opening for the passage of said closure member.
Claim 2
Dependent Claim
134 words
A condensation discharging device, comprising a flat thermic actuating member adapted to be filled with a volatile liquid, and comprising a diaphragm, a closure member centrally carried by said diaphragm, a valve seat adapted to be closed by said closure member, and two opposed rigid plate-like wall members, said wall members having annular clamping members spaced from their edges for tensioning and holding said diaphragm between the two wall members, the diaphragm being soldered to the two wall members at its outer edges, and a casing having passages for the inflow and outflow of liquid and enclosing said thermic actuating member, one of said wall parts and said diaphragm enclosing a space for receiving said liquid, the other one of said wall parts having a central opening for the passage of said closure member.
Claim 3
Dependent Claim
28 words
A device in accordance with claim 1, wherein the edge portions of said wall parts extending from said clamping members to the soldering extend away from each other.
Claim 4
Dependent Claim
27 words
A device in accordance with claim 2, wherein the diaphragm is preliminarily curved in such manner that it is devoid of tension in two positions of rest.
