摘要： PURPOSE:To prevent the occurrence of ignition and subsequent explosion due to leakage gas and a spark from a control function section, even if natural gas should leak at a natural gas flow passage, by providing a division between the control function section and the natural gas flow passage. CONSTITUTION:A gas introduction pipeline 17 led from a source tank or the like storing natural gas is connected to a gas introduction port 2. At the same time, a gas supply line 18 laid so as to be capable of communication with a cylinder on board a vehicle or the like is connected to a gas supply port 8. Also, a division of high airtightness is provided between a natural gas leak position and a group of a function control section 10, a display board 11, a switch 12 or the like, against an unexpected natural gas leak at a natural gas flow passage, at the time of compressing the natural gas approximately to 20MPa for charge. According to this construction, a concern is eliminated, regarding the ignition and explosion of leak gas, due to the section 10, the board 11, the switch 12 or the like acting as the origin of a fire.

摘要： PURPOSE:To provide a device capable of safely charging a small vessel with natural gas. CONSTITUTION:This natural gas charging device is formed out of a strainer 4, a nonreturn valve 5, an intake snubber tank 6, a compressor 7, a bypass solenoid valve 8, safety valves 9 and 10, and the like. In addition, the device has a three-way valve 3 between a coupling 1 for connection to a gas supply such as a gas tank and the strainer 4, so as to be capable of communication with the atmosphere as well. Thus, the device, when communicated with the atmosphere via the valve 3, can be completely isolated from the gas supply. As a result, even if a danger of gas leakage exists in the device, safety can be maintained for a charge standby stage. Also, natural gas between the nonreturn valve 5 and the three-way valve 3 can be released to the atmosphere, when the device is communicated with the atmosphere via the valve 3, thereby enabling the strainer 4 to be easily serviced.

摘要： PURPOSE:To reduce a consumption energy by a method wherein a waste heat recovery heat exchanger for recovering waste heat of a combustion device is disposed in a pipe for medium flowing from a heat radiation heat exchanger of an external combustion engine which is driven by heat of the combustion device. CONSTITUTION:As a rotating shaft 23 is driven by a motor of low output a high temperature side diaplacer 1 and a low temperature side disposer 2 are reciprocated with a phase of 90 deg. and then working gas is reciporcated within a heater 5. The heater 5 is being heated by a high temperature combustion gas continuously generated at a combustion device 24, so that the working gas reciprocating is kept at its high temperature state, remained high temperature combustion gas is heat exchanged with the combustion air in the air preheater 25 and further heat is supplied to the hot water with the waste heat recoverying heat exchanger 26, and the remained heat is discharged out of a discharging pipe 27 into the surrounding air. Accordingly, a heating capability is improved and at the same time the discharged heat recoverying heat exchanger performs a heat exchanging operation between the gas and liquid, so that a high efficiency of waste heat recoverying can be attained.

摘要： PURPOSE:To improve the performance of the whole body of a regenerative heat exchanger and to increase the efficiency of the engine by forming numerous sheets of wire-gauzes of two or more sorts with different heat conductivity, which are housed by superposing in a case. CONSTITUTION:In a regenerative heat exchanger 8 for high temperature and a regenerative heat exchanger 11 for low temperature, wire gauzes 36 and 37 formed of metallic wires with different heat conductivity are laminated alternatively, and housed in a case 8a and a case 11a. By using copper gauze 37 with a higher heat conductivity for the regenerative heat exchangers 8 and 11, the heat is transmitted to the inside of the wire-gauze, and the heat is accumulated effectively more than using a stainless gauze 36. Consequently, by superposing the stainless gauzes 36 and the copper gauzes 37 alternatively, the heat conductive loss can be suppressed in a low level as a whole while increasing the heat capacity, and the performance of the regenerative heat exchangers 8 and 11 can be improved.

摘要： PURPOSE:To reduce the thermal loss and to improve the engine efficiency by installing rings to seal the clearances between cylinders in which an operating gas is sealed, and pistons to partition the inside of the cylinders into two chambers of different temperatures, to the cylinders. CONSTITUTION:In a hot gas engine using a VM(Vuilleumier) cycle, pistons 1a and 1b to partition a high temperature chamber 10a and a middle temperature chamber 10b, and, a low temperature chamber 11a and a middle temperature chamber 11b, are provided respectively in a high temperature side cylinder 10 and a low temperature side cylinder 11 arranged in the square direction of an external combustion type engine 6, and at the clearances 2a and 2b of both chambers, rings 3a and rings 3b are provided in two steps respectively. In this case, the rings 3a and 3b are inserted and installed in ring grooves 4a and ring grooves 4b engraved at the upper parts of the cylinder inner walls 10c and 11c respectively. As a result, even though the pistons 1a and 1b perform reciprocating movement in the engine, the positions to partition two chambers of different temperatures are not changed, and a thermal loss flowing through the clearances and through the cylinder walls are reduced.

摘要： PURPOSE:To stably supply cooling water by a method wherein the flow amount of cooling water is reduced when the level of the cooling water in an evaporator goes below a predetermined value or the temp. of the cooling water flowing into an absorber goes below a predetermined value. CONSTITUTION:When a predetermined amount of the cooling water having a low temp. beyond the design operating range is supplied from a cooling water pipe 31, the interior of an absorber 5 is supercooled and the absorbing liquid being diffused from a diffusing means 22 is cooled more than necessary to reduce the pressure of the absorber 5. For this reason, since the pressure of an evaporator 4 adjacent to an eliminator 23 is abnormally reduced, refrigerant is vaporized in a large amount exceeding the reference amount, resulting in the shortage of the refrigerant in the evaporator 4. Therefore, when the level of the refrigerant 9 sensed by a level sensor S1 goes below a predetermined value or the temp. of the cooling water sensed by a temp. sensor S2 goes below a predetermined value, a control signal is produced by a control device 8 to activate a cooling water pump P3 to reduce its number of revolution, thereby reducing the supply of the cooling water to the absorber 5. In this way the supercooling trouble is solved to restore the refrigerant absorbing capacity to the original condition.

摘要： PURPOSE:To prevent a trouble by monitoring degree of progress of a malfunction of heat exchangers even in cooling, heating state in an absorption refrigerator having a plurality of heat exchangers. CONSTITUTION:In the case of a cooling operation, thermally operating fluid such as absorbent/refrigerant is circulated via heat exchangers, i.e., a heat exchanger 13, heat exchanger 9, a high temperature regenerator 5, a low temperature regenerator 11, a condenser 23, an evaporator 26 an absorber 1 to cool water 36b of conduits 35, 37 to cold water. In the case of a heating operation, the fluid is circulated via the regenerator 5, the absorber 1, the evaporator 26 to heat the water of the conduits 35, 37 to heated water. A CPU 50 calculates a logarithmic mean temperature difference from detected temperature values of temperature detectors D1-Dn, and converts a temperature different value to values for preset reference values for the respective conduits. The CPU 50 discriminates the values to malfunction stages such as less than 150%, 150-300%, over 200%, etc., by the exchangers, and displays them by colors to display degree of progress of the malfunction.
