Title: Thermal expansion valve
Inventor: KANEKO MORIO
IPC: F16K31/70
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of trouble at the time of low evaporating temperature by compensating a flow rate of a refrigerant at the time of low evaporating temperature when the evaporating temperature is below a given evaporating temperature. SOLUTION: In a temperature expansion valve 7, the degree of superheat of a refrigerant at an outlet of an evaporator 9 is maintained at a given value by controlling the circulating flow rate of the refrigerant in such a manner that the valve is opened or closed in response to a balance relationship between the pressure in a valve opening direction which corresponds to the outlet temperature of the evaporator 9 and a spring load of a counter spring acting in a valve closing direction. The counter spring comprises a given spring 39 which constantly produces a given spring load and a correction spring 61 made of shape memory alloy which decreases its spring load corresponding to lowering of the temperature of the refrigerant in response to the temperature of the refrigerant at an inlet of the evaporator.  When the temperature of the refrigerant at the inlet of the evaporator is lowered, the spring load of the counter spring is lowered corresponding to the lowering of the spring load of the correction spring 61 and accordingly, the given degree of superheat is lowered thus increasing the valve open rate and the flow rate supplied to the evaporator 9.

Abstract: PURPOSE:To exactly operate a cooling fan for long term by measuring the temperature of an object to be cooled, varying the operating voltage of the cooling fan in accordance with the temperature thereby controlling the rotating speed of the cooling fan, thereby preventing the deterioration of the cooling system. CONSTITUTION:A thermocouple is employed in a temperature detector 5, the detector 5 is mounted on an object apparatus 1 to be cooled, the temperature of the apparatus 1 is measured, and a temperature signal voltage 7 proportional to the temperature is transmitted to a voltage controller 6. The voltage controller 6 thus controls the signal voltage 3 supplied from the apparatus 1 in accordance with the signal voltage 7 and supplies the signal voltage 3 to the cooling fan 2 as the operating voltage 8 for the cooling fan. As the operating voltage 8 is varied, the rotating speed of the cooling fan 2 will change. Since the rotating speed of the cooling fan 2 is varied in accordance with the temperature change of the apparatus 1, the deteriorating period of the cooling fan 2 can be prolonged and the efficient cooling can be conducted.

Abstract: PURPOSE:To enable to detect vortex flow produced in a suction reservoir by a pump immersed in water of the suction reservoir accurately and in an extremely short while, by converting, for instance, pressure change caused by the vortex flow into an electric signal. CONSTITUTION:When vortex flows 2, 2a are produced in a suction reservoir 1, abnormal physical phenomenon, for instance, fluctuation of pressure takes place near a pump 4, and it is detected by a pressure detector 6. The fluctuation of pressure thus detected is converted into an electric signal by a transducer 7, whereafter it is amplified by an amplifier 8 and then transmitted to a correlation analyzer 9. The output signal of the correlation analyzer 9 is transmitted to a judging circuit 10 for judging the signal of an autocorrelation function, and the output signal of the circuit 10 is applied to an alarm circuit 11 for giving an alarm when vortex flows are produced in the suction reservoir. With such an arrangement, it is enabled to detect occurrence of vortex flows accurately and in an extremely short while, and at the same time, to make it unnecessary to survey abnormal operation of a pump at all times.
