Abstract
A thermodynamic condensate trap comprises a body 2 and a cap 18 which define a chamber 24. Inlet and outlet passage 8, 10 emerge into the trap chamber 24 at a seating face 12. A valve element in the form of a disc 26 is movable within the chamber 24 to open and close a flow path through the chamber 24 between the inlet passage 8 and the outlet passage 10. The cap 18 has thermal insulating means, for example in the form of air spaces 30, 32 to reduce heat transfer between the trap chamber 24 and the ambient surroundings. This reduces the cycle time of the trap, and consequently, extends the useful life of its components.
