摘要： A mixing valve apparatus is disclosed, for producing a mixed fluid of a desired temperature obtained by mixing high temperature fluid and low temperature fluid with each other. The apparatus includes a pressure-sensitive control unit (6) which operates in response to the differential pressure (.DELTA.P) between the inlet pressure of the low temperature fluid and the pressure of the mixed fluid, and which unit controls the opening degree of an inlet valve (V.sub.1) for the high temperature fluid. Pilot passage (R.sub.0 .about.R.sub.3) for communicating the inlet pressure of the low temperature fluid to said unit is provided with a throttle (L, L.sub.1) whose effective surface area varies in response to the temperature of the mixed fluid, to compensate the opening degree of the inlet valve (V.sub.1) for the high temperature fluid upon variation of the temperature of the mixed fluid.

摘要： A generator for an absorption refrigerator has heat transfer pipes within a shell main body, an absorbing solution injecting port and absorbing solution exhausting port. An absorbing solution exhausting port is provided which receives the absorbing solution flowing over a dam which is higher than the exhaust port on the absorbing solution injecting port side. A steam box is provided to cooperate with the absorbing solution exhausting port, which box has an opening above the top of the dam. The absorbing solution flowing in the main body injected from the injecting port (3) forms a closed type heat exchanger connected with an open type heat exchanger provided at the steam box into which the absorbing solution vaporizes as it flows over the dam (41) into the exhaust box (42).
