    • A condenser is provided that makes a liquid droplet of a liquid phase medium drop effectively, the liquid phase medium residing in a lower end opening of a medium passage of the condenser, thereby preventing any degradation in the performance of the condenser. In the condenser, vapor, which is supplied to a cooling pipe (14) connected to cooling fins (16), is cooled, condensed into water, and recovered in a water-collecting tray (21) provided beneath the cooling pipe (14), and a needle-shaped member (24) provided so as to face the lower end opening of the cooling pipe (14) ruptures the droplet that, due to surface tension, resides in the lower end opening of the cooling pipe (14) and makes it drop into the water-collecting tray (21). A plate-form filter can be used instead of the needle-shaped member (24), and in this case not only can the droplet be made to drop from the lower end opening of the cooling pipe (14) more effectively due to the capillary action of the filter, but also dust contained in the water can be removed.

    • In a Rankine cycle system for an internal combustion engine, including an evaporator (3) for generating a vapor, an expander (4) for converting a heat energy of the vapor into a mechanical energy, a condenser (5) for cooling the vapor discharged from the expander (4) to restore it into water, a tank (6) for storage of the water from the condenser (5), and supply pumps (7, 8) for supplying the water in said tank (6) to the evaporator (3) in a pressurizing manner, the water in the tank (6) is supplied via a water jacket (105) of the internal combustion engine (1) to a dispensing valve (106) by the lower-pressure pump (7). A portion of the water dispensed by the dispensing valve (106) is further pressurized and supplied to the evaporator (3) by the higher-pressure pump (8), and another portion of the water dispensed by the dispensing valve (106) is discharged to the tank (6) after dissipating its heat in an auxiliary (110) such as a heater for heating a vehicle compartment and the like. Thus, it is possible to sufficiently cool heated portions of the internal combustion engine (1) by the water which is a liquid-phase working medium, while maintaining the performance of the Rankine cycle system, thereby aiming at the disuse of a radiator.

    • When a flow of a working medium stagnates in an expander or evaporator of a Rankine cycle apparatus including a closed working medium circulation circuit, a high pressure exceeding an allowable maximum pressure level of the expander or evaporator is produced within the closed working medium circulation circuit. In such a case, the water-phase working medium is first discharged via relief valves out of the circulation circuit, so that the pressure within the circulation circuit can be lowered. Then, once vapor within the evaporator, having been lowered in temperature and pressure, flows backward within the closed working medium circulation circuit, the vapor is also discharged via the relief valves out of the circulation circuit. In this way, the pressure within the expander or evaporator can be reliably prevented from exceeding the allowable maximum pressure level.
    • 当工作介质的流动停滞在包括封闭的工作介质循环回路的兰金循环设备的膨胀器或蒸发器中时,在封闭的工作介质循环回路内产生超过膨胀器或蒸发器的容许最大压力水平的高压。 在这种情况下,水相加工介质首先通过溢流阀排出循环回路,从而可以降低循环回路内的压力。 然后,一旦蒸发器内的蒸气已经降低了温度和压力,就在封闭的工作介质循环回路内向后流动,蒸气也经由溢流阀排出循环回路。 以这种方式,可以可靠地防止膨胀机或蒸发器内的压力超过容许最大压力水平。
