ルすることは困難であった。(Prior art) For example, in a turbo compound engine, as shown in Fig. 4, the output shaft 2 of the diesel engine 1 is connected to the generator 3 and other loads, while the exhaust outlet of the turbine T of the exhaust supercharger 4 is connected to the It is connected to one turbine, and the output shaft 5 of the power turbine PT is connected to the other end of the output shaft 2 via a reduction gear mechanism 6, a multi-disc clutch 7, and a fluid coupling 8. The turbine T is connected to the engine 1 via an exhaust pipe 9, and the blower B driven by the turbine king is connected to the engine 1 via an air supply pipe 10. The fluid coupling 8 is used to prevent torque fluctuations of the diesel engine 1 from being transmitted through the reduction gear mechanism 6 to the power turbine P in an amplified state. When engine 1 and power turbine P cannot be recovered during idling operation, etc.
It plays the role of blocking T. Conventional fluid coupling 8
Due to its structure, the hydraulic oil cannot completely drain out, so it does not have a complete latch function (power cutoff function). Therefore, a separate clutch 7 is required. Further, since the fluid coupling 8 is a m-shaped structure in which hydraulic oil is introduced and discharged from the central portion, the structure is complicated, and it is difficult to control the transmitted torque at the fluid coupling 8 portion.

By controlling this, the purpose is to make the torque transmission characteristics variable and also to have a clutch function that reduces the transmitted torque to zero.

である。(Structure of the Invention) The present invention provides an external discharge hole for hydraulic oil that is always open in at least the outer periphery of the housing body surrounding the impeller of the fluid coupling, and a passage for supplying the hydraulic oil into the housing body. This is a fluid coupling model 81~luke control device characterized by being provided with a control unit that changes the amount from approximately O to a predetermined amount.

動油量を次第に増すと、伝達トルクは次第に増加する。When the amount of hydraulic oil in the housing body is reduced to approximately 0 by the operation of the control section, the transmitted torque becomes 0, which is equivalent to a state in which the clutch is disengaged at a temperature of hN. When the amount of hydraulic oil in the housing body is gradually increased, the transmitted torque is gradually increased.

This is an area where the output from the power turbine can be incorporated into the engine output when the subsequent exhaust residue is passed through the power turbine. In other words, the engine speed and output are high to some extent,
Therefore, the exhaust temperature is also relatively high.11 The sensor 35 and rotational speed pickup 36 in FIG. 1 detect the output recovery area A in FIG. 33
A signal is sent to the variable diaphragm 31, and the variable aperture 31 is opened.

A portion of the hydraulic oil flows out from the discharge hole 25 to the outside, and a portion of the remaining hydraulic oil flows out from the discharge hole 26 to ensure the minimum required oil level during operation. . When moving from area A to area B in FIG. 5, the variable throttle 31 is closed and hydraulic oil is no longer supplied into the housing body 16, so the oil level in the housing body 16 becomes O, and the fluid coupling is not used. The torque transmission function is lost, and it is as if the clutch is disengaged.

Functions can be used together. Particularly in the case of a turbo compound engine, by opening the variable throttle 31 in the range where the power turbine causes loss to the engine (region 13 in Figure 5), the problem of driving the power turbine from the engine side can be avoided and the power turbine can be reduced. It is possible to improve fuel efficiency. In addition, J in Figure 1: By providing an opening on the outer periphery of the fluid joint, it is possible to prevent residual fragrances (mainly 7J-bon, etc.) in the lubricating oil from forming an internal 1ff product due to centrifugal separation, so it contains a relatively large amount of residual fragrances. It becomes possible to divert the system oil of the diesel engine to the fluid coupling.
