Definitions

  • This invention relates to pumps or motors operating With liquids under pressure, and particularly with oil.
  • Fig. 3 is another longitudinal section showing the parts in the interior of the casing in oblique position.
  • the shaft 1 is supported by bearings 2 and 3 of an outer casing 22.
  • a coll'ar 4 is secured which carries radial pins 5.
  • These pins fit into balls 6 which are adapted to turn and to slide lengthwise on said pins, such balls being adapted to rock in suitable sockets of the pistons 7 but otherwise moving in unison with said pistons.
  • the pistons are of the-double-aeting type and adapted to reciprocate in suitable cylinders provided in an annular drum 8 through which the shaft 1 extends. In the particular position illustrated, the longitudinal axis of the drum coincides with that of the shaft 1, but normally, as explained hereinafter, the longitudinal axis of the drum intersects the axis of the shaft obliquely.
  • the drum is divided longitudinally, its sections being held together by a threaded ring 9, and is rotatably supported in a casing 10 by means of two ball bearings 11.
  • the outer ends of the cylinders in which the pistons 7 reciprocate communicate with chambers 12 each of which is closed by a drical drum 8 and the cover 13 of the sura piston 26 (Fig. 3) located diametrically rounding casing 15 control openings 17 are provided in communication with channels 18; the said channels are bounded on the one hand by the casing 10 and by a cylindrical inner body 19 on the other hand. .Furthermore the channels 16 and 18 communicate with one another by channels 20 in the casing 10.
  • the surrounding casing 15 is provided with hollow pivots or trunnions 21 which are either fixed or can be rocked and are supported in the stationary outer ring 22.
  • suitable adjusting means comprise an adjusting screw 24 arranged on one side of the outer casing 22, and
  • the device When used as a pump, the device operates as follows If the-shaft 1 is rotated and the surround ing casing 15 is disposed obli uely, or swung around the pivots 21 to an o lique position,
  • the pistons 7 located in the cylindrical drum 8 will reciprocate during each rotation as 16 said cylindrical drum supported on ball bearings can easily take part in the rotation of the shaft.
  • rounding casing 15 may be fixed to the outer casing 22 or madeintegral therewith. This may for instance be the case if the structure is employed as a fluid motor.
  • control openings are located on the inner cylindrical faces of the drum 8 and the cover 10, which faces move adjacent to each other.
  • said cylindrical faces may be worked easily and exactly said arrangement, besides showing a slight sliding speed, proves to be particularly advantageous for an exact con- -.trol of the pump or motor.
  • the cylindrical bearing faces gently tapering faces may be employed.
  • control openings may be arranged at the face of the cylindrical drum which arrangement, however, is less advantageous on account of the greater sliding speed and requires special devices for packing or tightening purposes.
  • a structure adapted for operation m conjunction with a fluid comprising a centralshaft, a rotary body provided with longitudinal cylinders and surrounding said shaft, pistons arranged toreciprocate in said cylinders, a casing forming a support for said rotary body andmounted to rock for adjustment about an axis transverse to the axis of rotation, and operativeconnections for causing reciprocation of said pistons to occur concurrently with the rotation of said shaft and said body.
