Abstract: A valve includes a housing defining therein a channel, a valve seat on an inner surface of the housing at a middle of the channel, a valve body member seated on and unseated from the valve seat to close and open the channel, and a stem spaced from the valve seat and rotatable around a first axis parallel with an opening surface of the valve seat. The valve body member and the stem respectively have a restricting hole and a restricting projection mutually slidably engageable to form a cam mechanism. The cam mechanism, in conjunction with rotation of the stem, reciprocates the valve body member between the seated position and the unseated position, and rotates the valve body member to be in a posture along a flow direction of a fluid flowing through the housing at the unseated position.

Abstract: In a system for reusing a thermal energy of an air discharged from a heated air source to heat a combustion air to be supplied into a combustion device so that the combustion air is mixed with a fuel to be combusted in the combustion device, an air feeder sucks the combustion air and feeds the combustion air toward the combustion device, an inlet passage at an upstream side of the air feeder passes the combustion air toward the air feeder, and the inlet passage includes a first inlet port for taking the air from the heated air source through the first inlet port into the inlet passage to incorporate the air to the combustion air and a second inlet port for taking an atmospheric air through the second inlet port into the inlet passage to incorporate the atmospheric air to the combustion air.

Abstract: A refrigerating machine including an evaporator section, absorber section, condenser section and a regenerator section respectively divided into two stages. The first evaporator stage and second evaporator stage are arranged so as to be enclosed by the first absorber stage and the second absorber stage, with the first absorber stage being combined with the first evaporator stage and the second absorber stage being combined with the second evaporator stage to respectively form separate units. The first low temperature regenerator stage and the second low temperature regenerator stage are arranged so as to be enclosed by the first condenser stage and the second condenser stage, with the first condenser stage being combined with the first low temperature regenerator stage, and the second condenser stage being combined with the second low temperature regenerator stage to respectively form separate units.

Abstract: An absorption type chiller/heater unit is actuated to generate cold water for air cooling and hot water for heating and/or hot water supply by utilizing, as a heating source, the exhaust gas from an internal combustion engine and the cooling water heated in and delivered from the water jacket. When generating the hot water for heating and/or hot water supply, the temperature of the engine cooling water delivered from the heat exchanger for heating and hot water supply is raised by a water heater to an appropriate level for the cooling of the internal combustion engine.
