摘要： PURPOSE: To have fine control of an oil-hydraulic pump/motor stably even in the range of revolving speed near zero by furnishing a control device at the oil-hydraulic pump between its pressure oil pipe and oil exhaust pipe, and by allowing this control device to keep the discharge amount at tilting angles near zero to specified levels.
CONSTITUTION: In this oil-hydraulic driving system, an oil-hydraulic pump 2 is driven by a prime mover 1, and driven member 4 is driven by the output oil pressure of said pump 2 through an oil-hydraulic motor 3. Thereby the revolving speed or output power of the drive shaft is controlled. Here a control device 8 is interposed between the oil exhaust pipe 6 and pressure oil pipe 5 of the hydraulic pump 2, to keep the discharge amount at tilting angles around zero to specified levels. That is, when the tilting angle of the hydraulic pump 2 has attained a set level, the valve incorporated in said control device 8 is opened to permit flow in a certain necessary amount. The tilting angle is now be fixed to such a point that the discharge amount from the hydraulic motor 3 will be a certain constant value. At this time, the valve of the control device 8 is controlled on the basis of the amount of oil required by the hydraulic motor 3.

摘要： PURPOSE:To contrive reduction of centrifugal stress of a dual flow turbine by providing a branch passage which is branched from a steam flow passage and led through the inside of a rotor to a nozzle at the final stage in the latter stage part of the turbine. CONSTITUTION:Steam which has been flowed into a turbine, which is accelerated by a nozzle in a partition plate 4, and converted to be rotational force with use of a mover blade 2. In other to have the final stage as dual flows so as to obtain high velocity rotation and high efficiency preventing the final stage from being maximum, steam at the inlet port in the final stage is divided into two, one is led to a final stage (a), and the other is led through a steam passage 5 to a final stage b. In this case, a proper inductor is arranged at the inlet port in the stem passage, and a blower is arranged at the outlet port. This facilitates to maximize the height of the mover blade at the final stage because a condensate turbine, etc. are big volumetric flow, and to reduce centrifugal stress in the turbine.

摘要： PURPOSE:To make it possible to operate each hydraulic control valve certainly, by inserting a multi-orifice in each feed line, so as to always allow a definite quantity of oil flow. CONSTITUTION:OSV1 is an oil feed control valve which feeds cooling oil to a high-speed fluid coupling FC1, OSV2 is also an oil feed control valve which feeds cooling oil to a low-speed fluid coupling FC2, and these OSV1 and OSV2 are equipped with multi-orifices NO1, MO2, as pilots, respectively. In this way, a possibility of closing the route by a foreign matter, can be excluded actually, by setting said multi-orifice in each cooling oil feed line. Then, a definite quantity of oil can always flows by always returning the oil to a tank through the multi-orifice, and consequently, each hydraulic control valve operates certainly.
