Definitions

  • Distributor pumps of this type are already known. Com-pared to distributor pumps whose distributing member is driven uniformly, progressive drive has the advantage that with equal time of rotation, or equal delivery interval respectively, a multiplication of the piston speed and so a considerable increase of suction and discharge preformance is achieved.
  • the purpose of the invention is to eliminate these drawbacks.
  • FIG. 1 shows an axial section through the lubricating p p
  • FIG. 4 a section of the lower part of the pump on line IVIV in FIG. 1, but with the driving shaft turned anticlockwise through 90;
  • FIG. 5 the same section as FIG. 4, but with the driving shaft turned anticlockwise through further 180";
  • FIG. 6 a diagram where, with reference to each other, are graphically represented, in the lower part the piston movement at A, /2, and full stroke, in the middle part the overlapping conditions of the control ducts, and in the upper part the intermittent movement imposed upon the distributor by the ratchet freewheel.
  • the distributor ends in a shaft 3 turning within a downward extension of the upper casing.
  • This extention comprises a frame-like part 1 forming a window 34 (FIGS. 4 and 5) for the mounting of a driving and reduction gear and ends in a tenon 1" which finds its target in an axial bore of the lower casing 35.
  • a lateral flange of the lower casing serves as bearing for the driving shaft 36 whose free end is provided with a slot for accommodating a rotary driver.
  • the driving shaft is fixed by a stud bolt 38 engaging in a circular groove provided on the shaft.
  • a second coil spring 47 engages with an eye 47 in the radial slot 48 of ring 15 and from there closely encircles the rotor almost completely anticlockwise in a shallow annular groove.
  • the oil discharges for internal lubrication into the upper casing by duct 30 rises to the horizontal shoulder of the rotor underneath ring 15, then through two symmetrically arranged vertical ducts 49 in the rotor, drains into the ring space 50 underneath the tapered part of the distributor and from here, through duct 51 in the bottom of the upper casing falls into the lower casing.
  • this locking mechanism is formed by an annular coil spring 47, retained with an eye 47 in a radial slot of ring 15 and from there encircles the upper part of the rotor counterclockwise. It thus opposes the undesired movement of the rotor in this direction considerably by jamming, whilst clockwise it is expanded and exerts only an insignificant friction on to the rotor which in .this direction, in the locked position of the ratchet gear, is positively driven by the driving shaft.
  • the same result could be achieved by an adequately arranged helical spring.
  • the distributor 3 In its rotation, the distributor 3 carries along with it in the slot 4 the lever 6 and the member 10. The latter slides with its ends under the cam track of ring 11 fixed to the casing. Whenever member resting on the middle part of piston 7 is pressed downwards by two diametrically opposite cams, it effects the descent of the piston. During this downward movement duct 31 connects the chamber 32 underneath the piston with a discharge duct 28. After the end of the descent of the piston and the expulsion of the oil, the tilting lever 6 in positive coaction with the piston, comes in touch with a set screw 16 and, rocking around pin 5, with its other arm and by means of pin 9 lifts the piston whereby the latter effects a filling stroke.
  • the advance steps should be adapted to the number of the discharge openings in such a way that the same optimal conditions are provided for all openings.
  • the ratchet wheel which is provided with 24 teeth is fixed to the rotor by means of pin 42 in such a way that each discharge stroke is accomplished in one course and the suction stroke is performed in two sections during two advance steps following one another with an interval (see diagram in FIG. 6).
  • the number of teeth of the ratchet wheel must be in an integral ratio to the number of outlets in the upper casing. In the described example there are 24 teeth and 8 outlets.
  • a distributor pump in particular for lubricating oil, comprising a pump body having a plurality of outlets therein and a rotary distributing member having control ports progressively driven by a rotary shaft, a piston guided in said rotary distributing member, a ratchet freewheel gearing provided on said shaft, a cam ring acting upon the said piston to effect the delivery strokes of the latter, cam-type heads of adjustable screws acting also on said piston to individually effect the filling strokes for each of said control ports, the number of teeth of the said ratchet wheel being an integral ratio of the number of outlets in the said pump body in order to adapt the advance steps of the ratchet free-wheel to the overlapping conditions of the said control ports sweeping over the inlet and outlet ducts in such a manner that each delivery stroke of the piston is accomplished during a single advance step of the ratchet free-wheel.
