Filed: 1987-05-28
Abstract: PURPOSE:To prevent the melting accident of a core beforehand, to secure the soundness of the core and a structural material and to increase reliability, by providing flow path deflecting plates, which deflect the flow of coolant into the circumferential direction in a core supporting mechanism and imparts turning streams. CONSTITUTION:A flow straightening grid 18 is provided in the vicinity of the upper end part of a core 8. A plurality of flow-path deflecting plates 19, which are curved in a radial pattern from the center, are provided at thermal shock preventing plates 17 at the lower end part of a core upper structure 10 through gaps between control-rod guiding pipes 20 and instrument wells 21. The curved surface of each deflecting plate 19 is formed in an arc pattern or in a radial pattern along the lower surface of each thermal shock preventing plate 17. Sodium 2b, which flows out of the core 8, rises up through the straightening grid 18. The flowing direction is deflected into the circumferential direction along the preventing plates 17 and the deflection plates 19. Therefore, the flow of the sodium 2b in a core supporting mechanism 9 becomes a large turning stream with the upper mechanism 10 as the center. Since the flowing direction is deflected into the circumferential direction along the deflecting plates 19, the flow toward a liquid surface 16 along the inner wall of the supporting mechanism is restricted. Therefore, waves do not occur on the liquid surface, thereby the involution of cover gas 15 can be prevented.

Title: Transmission for automobile
Inventor: OYAMA KAZUO
IPC: F16H47/02
Filed: 1994-06-13
Abstract: PURPOSE:To prevent the generation of a gear shift shock by providing a clutch for a gear shift to selectively establish a given gear speed between input and output shafts, a fixed capacity hydraulic pump operated based on a difference in the number of revolutions between a crank shaft and the input shaft, and a hydraulic circuit through which variable capacity hydraulic motors are interconnected. CONSTITUTION:When, in each gear speed, the inclination angle of the swash plate of the variable capacity hydraulic motor M of a hydraulic continuously variable transmission CVT is changed in a forward or a reverse direction, the gear shift ratio of each gear speed can be increased or decreased. When shift up from a first gear speed to a second gear speed is effected, a clutch 19 for first speed - second speed is disengaged and the number of revolutions of a main shaft 3 is reduced by the hydraulic continuously variable transmission CVT. This constitution synchronizes the number of revolutions of the counter shaft 4 with that of a counter second gear gear 17. Since, in this case, the hydraulic continuously variable transmission CVT is completely disconnected from the counter shaft 4 connected to a drive wheel, the torque change of the hydraulic continuously variable transmission CVT is transmitted to a car body and there is no fear of a gear shift shock being generated.
