New description: [New technical field] This creation is related to fluid transmission equipment. Further, especially an Ou Dan pump, which is swayed by two rotors that are axially parallel to each other. And the pistons are axially overlapped with each other, and the pistons are reciprocated to pump the fluid. [Prior Art] A pumping structure for pumping a transport fluid can be roughly classified into a gear type, a piston reciprocating pump, a centrifugal type, etc., wherein a gear rotary pump and a live multi-pump pump This two-year-old Pu, due to the combination of the single, is commonly used in the Liko Weipu pressurized pump to send liquid _ occasion, shot, gear pump is affected by the tightness of the gear merging, and the pumping efficiency is not enough to meet The problem of pumping demand is more secretive. For the case where high pressure fruit feeding liquid f is needed, the reciprocating pumping is often performed; the operation of the piston reciprocating pump is mainly by the piston reciprocating in the red cylinder. And with the configuration of the inlet and outlet = to achieve the purpose of pumping the fluid, _, the piston is in the same place, the piston and the cylinder are read and rotated, so that the motor and other power tools drive the pump to operate. Effect cool (four) - end displacement and rapid deceleration to reach the stroke = re-cylinder (9) - end reverse plus catching Λ 'such vibrations easily accelerate the machine to produce fatigue. At the same time, the pipelines of the one-way reversed red cylinder are separately installed, and the purpose of the domain_New_ is relatively complicated, and it can only pump the fluid from the source end to the destination end in one direction. It is not possible to choose the direction of the pumping change, and the actual application forms a limit; if the direction of the fluid change is required, the inlet pipe and the outlet pipe which are respectively connected to the two one-way check valves need to be re-matched, or mutually It is not convenient to change the fluid inlet and outlet pipes that are connected to each check valve. It is not convenient to change the state of these pipes or the backstop _ setting state. If the face is inadvertently misfitted, it is easy to cause the threat. Leakage on the _, material pumping efficiency, so the scale knows that the fluid pump in the ease of use 'there is still further improvement. In view of this, the creators of this case continue to research and improve, and after repeated trials, there are more innovative and progressive creations. [New content] The main purpose of this creation is _ supply-槪: axial parallel And the two-axis non-synchronous-two-rotor respectively = and the respective Zhao-axis (four) are overlapped, and the two movable shafts are moved to further change the body of the pumping chamber into and out of the pump. The fluid pumping is smooth.

The first and second flow passages (23) (24) are perpendicular to the axis of the base (2) (30), and the first and second flow passages (23) (24) are perpendicular to the axis of the respective cover body (10) (30), and the first The second-axis (23) (24) M366612 has an axis pointing perpendicular to the axis of the brother, a hole (21) (22), and the first and second channels (23) (24) are respectively connected to the outside. The first and second flow passages (23) (24) are respectively connected to the fluid transfer pipelines, and a third flow passage (25) and a fourth flow passage (26) are formed inside the base (20). The third flow passage (25) is in communication with the first flow passage (23) and the respective pivot holes (21) (22), the fourth flow passage (26) and the ΔHai second flow passage (24) and the respective pivot holes (21) (22) connectivity The fluid is caused to enter and exit the base (20) through the first and second flow passages (23) (24). As shown in the first to sixth figures, the first rotor (4〇) pivots to the first pivot hole (21), and the first rotor (40) axially protrudes and a drive shaft (41) pivots through the first A cover body (10) extends to the outside, and a power device (not shown) such as a motor or an engine is swayed to move the drive shaft (41) for rotation of the first rotor (4〇). The rotor (7〇) pivots to the second pivot hole (22), and the second rotor (70) axially protrudes from a pivot shaft (71) pivoted to the second cover body (3〇), thereby positioning the rotor a second rotor (70), and the first and second rotors (40) are in axial contact with each other, and the first rotor (40) opens a first slide (42) along a radial direction thereof. The second rotor (7〇) defines a second slideway (72) along the radial direction thereof, and the Ludi (7) track (42) and the second slideway (72) are axially perpendicular to each other, and the first Two slides (42) (72) adjacent to each other, the pistons (50) (60) respectively, an elongated rod body, the first and second pistons (5 〇) (6 〇) are axially perpendicular to each other and are in phase Fixedly, the first piston (50) pivots to the first slide (42), and the second piston (60) pivots to the second slide (72), The first and second pistons (5〇) (6〇) have axial lengths shorter than the respective slides (42) (72), respectively, so that the first rotor (4〇) & (5G) (10)) respectively reciprocatingly sliding along the respective slides (42) (72) 1 , and the second rotor (7G) is rotated by the third piston (70) to move the fluid Each flow channel (23) (24) (25) (26) M366612 enters and exits the base (20) for pumping fluid. Riding, the drive shaft (4) is borrowed by the bearing (43) and the first cover (10). The pivot (10) is also pivoted by the bearing (73) and the second cover (3〇). Wire rotor (10) (10) rotation touch; Na moving shaft (4)) More-step shaft set - shaft seal (44), for the prevention of fluid leakage. When the power unit such as a motor or an engine shakes the rotation of the first rotor (10), the first rotor (40) rotates the first piston (5〇), because the first piston (10) and the second piston (10) are mutually Then, the rotation of the first piston (5〇) drives the rotation of the second piston (10). The rotation of the second piston (10) drives the rotation of the second rotor (70). Furthermore, due to the first and second rotors (40) (10) axially parallel to each other, and the first and second rotors (10) (10) are respectively guided by the first and second covers (10) (10), so that the first and second rotors (10) (10) rotate 'the first piston (10)) At the same time, following the axial reciprocating slip of the first slide (42), the second rotor (10) rotates while following the axial reciprocating slip of the second slide (72); in other words, the first The first and second rotors (10) (10) and the first and second piston systems of the Oldham Coupling operate in opposite directions. • Please refer to the fifth, seventh, eighth and ninth diagrams. When the first rotor (10) is along the drawing, the first piston (5()) reciprocates axially along the first slide (42). Displacement, at this time, the first slide (42) is private to the first piston (50), forming a change in the spatial valley product, so that the "il body can be caused by the second flow path (25) Flowing the first-slide (42), and as the first rotor (40) rotates, the fluid flowing into the first slide (42) is directed by the first piston (50) to the fourth flow path (26) squeezing the push, so that the external fluid can be sucked into the pump through the first flow path (23), and the second M366612 " π · road (24) is pushed out 'To achieve the effect of the fluid.
