- the movement of the valve stem 72 is limited to straight movement by the valve stem guide 73.
- the direction in which the valve stem 72 moves linearly is the axial direction (longitudinal direction) of the valve stem 72.
- the valve body 71 moves integrally with the valve stem 72.
- the valve stem guide 73 is fixed to a fixing member 33 such as a casing, and the valve stem guide 73 and the valve stem 72 block the opening end of the flow path 76 opposite to the working fluid inlet 75a.
- the cam 80 is composed of a concave curved surface.
- the cam follower 81 moves according to the shape of the cam 80, and the valve rod 72 and the valve body 71 move together with the cam follower 81. That is, when the scoop tube 30 moves, the valve body 71 moves in the flow path 76 of the housing 75.
- the working fluid cooled by the fluid cooling device 26 flows into the flow path 76 from the working fluid inlet 75 a of the housing 75 through the upstream section 27 a of the working fluid circulation line 27.
- the working fluid passes through the working fluid outlet 75 b of the housing 75 and is supplied into the fluid chamber 5 through the downstream section 27 b of the working fluid circulation line 27.
- a plurality of working fluid outlets 75 b are formed at equal intervals along the circumferential direction of the housing 75. Although three working fluid outlets 75b are illustrated in FIG. 2, the number and shape of the working fluid outlets 75b are not limited to the present embodiment.
- the valve element 71 is slidably disposed on the inner surface of the housing 75 that forms the flow path 76. More specifically, the valve body 71 is disposed at a position where the valve body 71 covers a part of the working fluid outlet 75b. Therefore, the flow rate adjusting mechanism 60 can adjust the flow rate of the working fluid flowing through the working fluid circulation line 27 by changing the position of the valve body 71 in the housing 75. As shown in FIG. 2, when the cam follower 81 contacts the central region of the cam 80 having a concave curved surface, the opening area of the working fluid outlet 75b is the largest.
- FIG. 3 is a view showing the cam 80 and the cam follower 81 when the scoop tube 30 moves forward, that is, when the scoop tube 30 moves radially outward of the impeller 1 and the runner 2, and FIG. 4 shows the scoop tube 30 retracted.
- the cam 80 and the cam follower 81 are shown.
- the cam follower 81 When the scoop tube 30 moves forward or backward from the position shown in FIG. 2, the cam follower 81 is pushed by the cam 80, and the valve rod 72 and the valve body 71 move together. At this time, the valve body 71 moves in a direction to close most of the working fluid outlet 75b. As a result, the flow rate of the working fluid circulating through the working fluid circulation line 27 decreases.
- the cam follower 81 In the example shown in FIGS. 3 and 4, the cam follower 81 is in contact with the end region of the cam 80 having a curved surface. At this time, the opening area of the working fluid outlet 75b of the housing 75 is the smallest. The working fluid outlet 75 b is not completely closed by the valve body 71, and the working fluid is always supplied into the fluid chamber 5.
- the pressure of the working fluid flowing in the flow path 76 of the housing 75 acts on the valve body 71. Therefore, when the scoop tube 30 moves in a direction in which the cam follower 81 moves toward the central region of the cam 80, the valve follower 71 moves in a direction to open the working fluid outlet 75b while the cam follower 81 pushes the cam 80. As a result, the flow rate of the working fluid circulating through the working fluid circulation line 27 increases.
- the valve body 71 is formed with a plurality of pressure equalizing holes 71 a extending in the axial direction of the valve rod 72. These pressure equalizing holes 71 a are through holes, and are arranged at equal intervals in the circumferential direction of the valve body 71. When the valve body 71 moves, a part of the working fluid moves through the pressure equalizing hole 71a, so that the valve body 71 can move smoothly. Accordingly, it is possible to prevent a large load from being applied to the scoop tube 30 from the cam follower 81 when the scoop tube 30 moves.
- the slip loss is small. Therefore, the operation is performed to reduce the stirring loss of the working fluid and improve the efficiency. A smaller fluid flow rate is preferred.
- the cam follower 81 when the cam follower 81 is in contact with the end region of the cam 80, that is, when the output shaft 12 is rotating at high speed or low speed, the amount of the working fluid flowing through the working fluid circulation line 27. Can be reduced. Therefore, the efficiency of the fluid coupling can be improved.
- the cam 80 that can move integrally with the scoop tube 30 is provided, and the valve rod 72 has a simple structure in which one end of the valve rod 72 is brought into contact with the cam 80. It is not necessary to provide an actuator.
- the present invention can be used for a flow rate adjusting mechanism for adjusting the flow rate of the working fluid of the fluid coupling.
- the present invention can be used for a fluid coupling including such a flow rate adjusting mechanism.
