| PURPOSE: To reduce shock which is put on a metallic backing pinion by combining a plastic piston and the metal piston with a spring. CONSTITUTION: A connecting spring 13 is installed in a recessed groove 12 of a backing pinion 3a and attached to the pinion 3a by two pins 14, 15 which are installed in holes 16, 17 provided by being penetrated through one end of the connecting spring 13 and holes 18, 19 bored at a bottom of the recessed groove 12 respectively. A pin 21 is attached to a hole 20 provided at an another end of the connecting spring. The pin 21 is engaged with a hole 22 provided at a plastic pinion 1a inactively and extended in a hole 23 provided in a pinion 3a. The pin 21 is inserted in a pinion 1a without play, but the pin 21 has an idle clearance 24 to the hole 23. The pinion 1a and the pinion 3a can be moved with the relative angle around a common axis by the idle clearance 24. Thereby, a thrust transmitted to the pinion 3a through the pinion 1a is reduced, then a friction is reduced. | ||||||

| PURPOSE:To obtain a pump of small size and light weight able to perform smooth action by slidably fitting fan-shaped vane plates (piston), whose center is connected by a hinge, to a hole of a groove radially provided from the center respectively of a pair of rotating split balls. CONSTITUTION:A pair of split balls 4, 5 having a drive shaft 6 and a driven shaft 7, are rotatably housed in two-split spherical vessels 1, 2, being mutually swivelably connected through a small ball 3 arranged in the center of the vessels 1, 2. The drive shaft 6 and the driven shaft 7 are arranged in a manner wherein their axial line cross at a predetermined angle. While connecting both the split balls 4, 5 by fan-shaped vane plates 7, 9 connecting their center by a hinge, each vane plate 8, 9 inscribes its upper surface to the vessels 1, 2 and circumscribes the bottom surface to the small ball 3. Further for preventing the vane plates 8, 9 from deflecting, a center hinge pin 10 is extended being fitted to a small piece 11 slide rotating in a groove of the small ball 3. | ||||||

| PURPOSE: To eliminate vibration and noises and enhance cycle efficiency, by providing a rotary blade, a partition blade and other constituent members to construct a spherical moving mechanism centering the spherical center of a cylinder. CONSTITUTION: When a rotary shaft 2 is rotated by a motor 21, a rotary blade 4 is revolved in the same direction centering an axis P-O and a sphere chord X-X' is revolved on a plane perpendicularly intersecting the axis P-O. At that time, a partition blade 6 rotates around the center O of a sphere while rocking, and a sphere chord Y-Y' is also revolved. A rotary blade 5 is revolved together with a rotary shaft 3 centering an axis Q-O. As a result, the capacity of four chambers in a cylinder 1 partitioned by the rotary blades 4, 5 and the partition blade 6 is varied between zero and the maximum value. At that time, a lubricant in tanks 22, 24 is injected through inlet passages 20, 23, 19a, 19b and injection ports 17a, 17b. COPYRIGHT: (C)1981,JPO&Japio | ||||||
