摘要： PURPOSE:To shorten the time required for filling a head tank with an oil, by a method wherein a check valve and an orifice are provided for an oil-supplying pipe provided at a lower part of a head tank, and a vent hole opened and closed in accordance with the amount of the oil in the tank is provided at an upper part of the tank. CONSTITUTION:In starting a rotary machine, when an oil pump 2 is started, the oil is supplied into the head tank 4 through the oil-supplying pipe 6. In this case, the check valve 13 provided at the lower part of the head tank 4 is opened to obtain a sufficient passage. A float 11 is provided at an upper part of the interior of the tank 4, and is lowered to open the vent hole 12 when the tank 4 is not filled up with the oil, while it is moved upward to close the vent hole 12 when the tank 4 is filled up with the oil. In an emergency, the oil is supplied to a part 3 to be supplied with the oil through the orifice 14 provided at the check valve 13, in which case the vent hole 12 is opened again.

摘要： PURPOSE:To uniformize operating forces for rotation and slanting and to reduce the size and improve the operability by providing the integrated mechanism which operates separately by a column and shafts for the rotation and slanting. CONSTITUTION:The hollow column 3 is provided on the top surface of a lower base 1, a rotation hole 29 wherein the hollow column 3 of the lower base 1 can be mounted and a couple of shafts 27 for slanting and moving a device main body 2 are provided in the center of a tilt base 7, and the device main body 2 is provided with a couple of lock parts 20 which engage the shafts 27 of the tilt base. Then, the device main body 2 is supported rotatably by the engagement between the hollow column 3 on the top surface of the lower part 1 and the rotation hole engagement part 29 of the tilt base 7 and the device main body 2 is supported in an inclinable state by the engagement be tween the couple of shafts 27 provided on the tilt base 7 and the engagement parts 20 provided to the device main body 2. Consequently, the device main body can be rotated and slanted with the uniform operating forces without being moved and the rotating and slanting mechanism can be reduced in size on the whole.
