摘要： A vane type fluid machine includes: a casing; a rotor rotating in the casing; and a plurality of vanes supported by the rotor to slide on an inner surface of the casing. A seal portion of each vane is formed to be elastically deformable so as to slide on the inner surface of the casing while bending backward of a rotational direction of the rotor. Therefore, an improved structure of the seal portion of each vane secures good sealing performance even if machining accuracy of the inner surface of the casing is alleviated.

摘要： In a drive system, there is provided a waste heat recovering device forming a Rankine cycle by an evaporator for heating water with waste heat of an internal combustion engine to generate high-pressure vapor, the internal combustion engine being connected to a transmission, a displacement-type expander for converting high-pressure vapor generated by the evaporator to an output with constant torque, a condenser for liquefying low-pressure vapor discharged from the expander, and a feed pump for supplying water liquefied by the condenser to the evaporator. The expander is connected to a power generator/motor via a planetary gear mechanism, and the expander is connected to an output shaft of the internal combustion engine via the planetary gear mechanism and a belt-type continuously variable transmission. A change gear ratio of the belt-type continuously variable transmission is controlled such that a rotational speed of the internal combustion engine and a rotational speed of the expander are matched with each other and are transmitted to the transmission. Hence, it is possible to effectively drive the driven portion by using the output of the expander of the waste heat recovering device.

摘要： 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.
