Title: Clutch control device
Inventor: TAKANO TAKAO
IPC: F16D48/02
Filed: 1987-07-07
Abstract: PURPOSE:To improve the reliability by connecting one of cylinder chambers of a cylinder of a hydraulic device interlocking with a clutch releasing pneumatic actuator through a closing valve to an oil tank; and connecting both the cylinder chambers with each other through a clutch engaging operation controlling valve. CONSTITUTION:When an electromagnetic selector valve C is operated to feed a pressure air in a tank 2 to a pneumatic actuator 5, a rod 12 is moved rightwardly to release a clutch. At this time, oil in an atmospheric pressure chamber 40 is fed through an electromagnetic closing valve B to an oil pressure chamber 7 by the rightward movement of a piston 11, and an excessive oil is returned through a restriction of an electromagnetic closing valve 27 to an oil tank 3, thus suppressing enter of the air in an atmospheric air chamber 32 into the oil pressure chamber 7. Next, when the electromagnetic selector valve C is returned, the pistons 11 and 15 are moved leftwardly by a return spring of the clutch, and the oil in the oil pressure chamber 7 is fed to a hydraulic cylinder 29 to close a control valve 30. At this time, an electromagnetic closing valve A or B is duty-controlled to return the oil to the atmospheric pressure chamber 40, thereby controlling a clutch engaging operation. Thus, the reliability of the hydraulic device and the control accuracy of the clutch may be improved.

Filed: 1984-08-17
Abstract: PURPOSE:To obtain excellent precision by determining distances between a reference water level and an upper and a lower pressure outlet tap so that pressure variations in saturated steam specific gravity gammas and saturated can water specific gravity gammaw cancel each other. CONSTITUTION:When a drum water level is almost at a reference value, the sealed drum type level gauge determines the distance H1 between the reference water level and upper pressure outlet tap and the distance H2 between the reference water level and lower pressure outlet tap so that pressure variations in saturated steam specific gravity gammas and saturated can water specific gravity gammaw cancel each other. In this case, differential pressure DELTAP is shown by an equation, where gammaa is the specific gravity of the water in a reference leg and has almost no dependency on the drum pressure P. Further, H1, H2, (b), and (d) are constants. For the purpose, the ratio of H1 and H2 is so selected that aH1- cH2=0, and then the influence of pressure upon the differential pressure DELTAP is eliminated, thereby obtaining excellent precision.
