<p>PURPOSE:To make a discharge fluid rate alterable at will, by securing a spherical body tight to an input shaft being connected to a motor output shaft, while setting up a driving swash plate rockably on the circumference of this spherical body. CONSTITUTION:An input shaft 4 is shiftably connected to a motor output shaft 3 axially, while a spherical body 6 is secured tight to a tip end of the input shaft 4, and a fulcrum shaft 7 is solidly connected to the input shaft 4 of the spherical body 6 and a part at the opposite side as one body, while a driving swash plate 9 is supported on the circumference of the spherical body 6 so as to cause it to be solidly rotated by a Woodruff key 10 and to make it rockable axially. With this constitution, following rotation of these output and input shafts 3 and 4, a tilt angle in the driving swash plate 9 can be altered without altering the bottom dead point position of a piston 26 to be driven for reciprocation by the driving swash plate 9 so that the quantity of the fluid discharged out of a pump chamber 34 can be optionally altered.</p> |
