摘要： PURPOSE:To miniaturize and simplify a mechanism in a title air conditioner heat pump by supporting with a coiled spring disposed in a buffer chamber one of low and high temperature side displacers such that they reciprocate with a predetermined phase difference, and constructing a forced vibration system with pressure variations of each operating gas and with a pressure difference in the buffer chamber. CONSTITUTION:A high temperature side buffer chamber 33 is provided in a high temperature side intermediate temperature space 13 of a high temperature cylinder 1, and a crank 4 is coupled with a high temperature side displacer rod 3 to reciprocate a high temperature side displacer 2 by the rotation of the crank 4 for production of pressure variations of operating gas. In contrast, low temperature side buffer chamber 30 is provided in a low temperature side intermediate side buffer clamber 30. Further, a 90 phase difference is produced between the high and low side displacers 2, 7 by the pressure of the high temperature side operating gas and the force of the spring 29.

摘要： PURPOSE:To carry out a good performance of combustion at a specified excess air factor in compliance with the rate of air blow by conducting the control on the basis of the wind amount sensing output and the temp. sensing output so that the ratio of the amount of fuel supply to the rate of air blow. CONSTITUTION:The rate of air blow Qa is proportionate to the difference of the pressure Pc in a combustion chamber 26 from the atmospheric pressure Po. This provides measurability for the pressure Pc in the combustion chamber with respect to the rate of air blow Qa in compliance with a temp. signal given by a temp. sensor 29, which represents the gas temp. in the combustion chamber 26, to give information about the electrical amount to be fed to an electronically controlled gas proportioned valve 15 for obtaining the rate of fuel flow in accordance with the rate of air blow Q. In this manner the rate of air blow to the combustion chamber 26 and the temp. representative for the chamber are sensed, and on the basis of outputs therefrom an electrical amount is fed which shall be corresponding to the proportioned valve 15 with governor function used for supplying the fuel, and thus the excess air factor is adjusted.

摘要： PURPOSE: To stabilize the output of a Stirling heat engine by providing at its output an electric load for controlling the rotation of this engine to hold its load const. CONSTITUTION: For driving a heat pump with a Stirling engine 1 as a power source, a rotational speed sensor 12 provided on the output shaft of the engine 1 measures the rotational speed variation of the engine 1 due to the variation of an air conditioner load or outside light, a field regulator 13 adjusts the field system of a generator 14 also provided on the output shaft and this generator 14 controls the rotational speed of the engine 1. Thus the electric load compensates the increment/decrement of the heat pump load, thereby always holding the entire load const. to result in a stable heat pump system.

CONSTITUTION:In a crank shaft-type Sterling engine arranged with two pistons in series in a cylinder, the pressure flucturation generated in a cylinder 16 (the pressure generating mechanism is omitted) is applied to a power piston 15, is converted to a force, and is transmitted to a crank shaft 7 via a power piston rod 14, a crosshead 13, and connecting rods 11, 12. A displacer piston 22 is reciprocated by part of the rotating force of the crank shaft 7. An oil absorber 17 having permeability and absorptivity is provided in a space between the crosshead 13 and power piston 15. This oil absorber 17 can absorb the oil scattered from the crosshead 13 side or the oil stuck to the rod 14.
