According to the present invention according to the principle of lever lever starting from the left and right movement limit lines 58 and 59 of the fork lever 23 according to the position of the crank pin 25 and the groove 27 of the fork lever 23 interlock. In the portion where the operating force of the fork lever 23 acts small (corresponding to the upper to middle portion of the groove 27), the suction stroke of the pump is performed, and the portion where the operating force of the fork lever 23 acts large (the groove 27). In the middle to bottom), the discharge release of the pump is carried out to cover the maximum load of the pump, so that the lever principle can be effectively used in the operating range within the limited operating mechanism of the rotating machine.

Next, the operation sequence of the single vane rocking pump of the present invention will be described with reference to FIGS. 1 and 5.

First, when the drive shaft 14 rotates, the gear 16 rotates together with the flywheel 12, and as the gear 16 rotates, the gear 28 also rotates, together with the crank fly wheel 22 and the crank pins. 25 becomes interlocked. The eccentric rotation of the crank pin 25 is converted to the rocking motion of the fork lever 23 and repeats the rocking motion about the drive shaft 20 as well as the single vane 40 together with the fork lever 23.

The process from (1) of FIG. 5 to (3) of FIG. 5 is a discharge stroke in which the single vane 40 moves from the right shift limit line 59 to the left shift limit line 58, and at the same time On the right side, the first suction stroke proceeds. At this time, the check valve 45 is opened while the first suction stroke for receiving the working fluid sucked from the outside through the suction hole 36 to the pump chamber right space 54 through the suction hole 43 is made. ) Is closed by the internal pressure of the pump chamber left space 53, and the working fluid filled in the pump chamber left space 53 remains open with the check valve 52 through the discharge hole 50 of the lower wall 38 of the pump chamber. The discharge stroke and the primary suction stroke are continued until the single vane 40 moves to the left limit line 58 as shown in (3) of FIG. 5 and discharged to the lower space 55.

Next, the process from (3) to 5 (1) in FIG. 5 is a suction stroke in which the single vane 40 moves from the left travel limit line 58 to the right travel limit line 59. As shown in FIG. The working fluid which is filled in is drawn into the pump chamber left space 53. At this time, the check valve 48 attached to the single vane 40 is opened and the check valves 45 and 52 are closed.

As the crank pin 25 rotates in the eccentric rotation of the fork lever 23 and the single vane 40, the above-described discharge and suction stroke continues. In addition, the pressurized working fluid stored in the lower space 55 is supplied to the required place through the discharge hole (37).

At this time, the operating angle α of the fork lever 23 and the single vane 40 is 30 degrees, and the axis of the crank pin 25 at the discharge stroke start point (suction stroke end point) from the shaft center C of the fork lever 23. Distance a _{1 to} (C "), distance a ₂ from the shaft center C to the shaft center C" of the crank pin 25 at the bottom of the operation of the crank pin 25, the shaft center C Distance (a ₃ ) from the discharge stroke end point (suction stroke start point) to the shaft center C "of the crank pin 25, and the crank pin 25 at the operating top of the crank pin 25 from the shaft center C. Distance a ₄ to the shaft center C ″, vertical distance a ₅ from the shaft center C to the line passing through the shaft center of the drive shaft 23 ', and the shaft from the shaft center C' of the single vane 40 These distances a ₁ , a ₂ , a ₃ , in the radius r ₁ to the outer circumference of the portion 41 and the vertical distance r ₂ from the axis center C ′ to the bottom of the single vane 40. _{a 4, a 5, r 1} , r 2) principle of leverage when the mutual relationship between the be: The single vane oscillating pumps have the maximum effect of using.

In the above relationship, the voltage force acting on the compression surface area of the vane 40 in the pump chamber during the operation of the pump 1 is the stress acting on the fork lever 23 by the principle of the lever, and the crank pin ( 25% of the voltage force at the position of the center of gravity C "at the highest point of operation, 30% of the voltage force at the position of the center of gravity C" at the discharge stroke start and end points (end and start of the suction stroke), crank At the center of the shaft (C ") at the bottom of the operation of the pin 25, 24% of the above-mentioned voltage force acts respectively, so that the required power of the pump 1 is not reduced at the time of suction stroke without reducing the discharge pressure and the discharge pressure of the working fluid. Approximately 23.6% can be mitigated, at least 32.2% in emissions.

According to claim 3, In the structure consisting of the fork lever 23, the crank pin 25 and the single vane 40, the operating angle (alpha) of the fork lever 23 and the single vane 40 is 30 degrees, The distance a ₁ from the shaft center c of the fork lever 23 to the shaft stroke c " of the crank pin 25 from the discharge stroke start point (suction stroke end point), and the crank pin 25 of the crank pin 25 from the shaft center c. crankpin axis (c ") distance to (a _2), in the exhaust stroke end point (the intake-stroke starting point) from the central axis (c) a crank pin (25) the central axis (c of" in operation the lowermost distance to) (a ₃ ), The distance (a ₄ ) from the shaft center (c) to the shaft center (c '') of the crank pin (25) at the operating maximum of the crank pin (25), the shaft center of the drive shaft (23 ') from the shaft center (c). Vertical distance a ₅ to the passing line, radius r ₂ from the axial center c 'of the single vane 40 to the outer periphery of the shaft portion 41, and single vane 40 from the central center c'. The correlation between the vertical distances r ₂ to the bottom of r ₂ = ₃ r ₁ = a ₄ ,

Method of manufacturing a single vane rocking pump using the principle of lever made to have a relationship.
