Abstract

PURPOSE:To exhibit vibration isolating effect by disposing cylinders incorporating a compression spring and a piston and having an orifice in an oil path connected to an oil pot, which are radially extended from the pump shaft center, and supporting the outer periphery of a steady bearing by pistons. CONSTITUTION:A steady bearing 13 supporting a bearing collar 5 fixed to a pump shaft 2 is fitted in a ring-shaped groove of a bearing support, and cylinders 15a-f are provided on the bearing support radially extending from the shaft center of the pump shaft 2. Pistons 16a-f fitted in the cylinders 15a-f are pressed to the outer periphery of the steady bearing 13 by compression springs 17a-f, and orifices 20a-f are disposed in oil paths 19a-f extending from the cylinders 15a-f to an oil pot 18. Accordingly, a displacement of the pump shaft 2 due to a temperature change can be followed up not to produce bending stress, a sudden displacement of the shaft center of the pump shaft 2 is restrained so as to exhibit a vibration isolating effect.
