れ、安定した流量の流体供給が可能となる。When the camshaft 5 of the dual constant-velocity reciprocating cam with 414 configurations as in the Kamishi is rotated at a constant speed, as the heart cams 1 and 2 rotate, the rotors 11 and 12 roll and rotate. Rod 7.
8 to reciprocate at a constant speed. Each heart cam 1, 2 home 1
The case is slightly longer than the return trip, so for example, rod 7
While the forward motion continues, the rod 8 having a phase difference of 180 degrees completes its backward motion and shifts to a retracting motion. After the mJ advance interlocking of both rods Otsu 8 was carried out suddenly for a while, rod 7 was moved to Otsu II! Enter military action. When the rod 8, which performs such a forward movement, is connected to each piston (not shown) of a fluid pump having two sets of valve mechanisms and operated, the fluid discharged from both discharge ports is , it is delivered at a constant flow rate and in a pattern in which both ends of the discharge stroke overlap. Therefore, the laminar flow of the discharged fluid is flattened, making it possible to supply fluid at a stable flow rate.

要である。29 and 30 are follower rods, each of which has a rolling wheel 31.32 connected to one end with a connecting pin 33.34, and a cam rf
It is fitted in 24. As the plate cam 21 rotates at a constant speed, the rods 29 and 30 reciprocate at a constant speed with a phase difference of 180 degrees. In this embodiment, the rolling 31,
32 is restrained in the cam grooves 23 and 24 and transferred,
The rod does not separate from the cam due to the rotational depth of the flat cam 21, and there is no need for a compression spring for pressure contact.

41 is a cylindrical cam, and there are two cam grooves 45 on the side.
44 is provided and rotated at a constant speed by a camshaft 45. 47,
48 is a follower rod, each with one end (with a rolling wheel 49
The couplings 50 are connected by connecting pins 51.52 and fitted into cam grooves 43.44 at opposite positions on the cylindrical side surface. As the cylindrical cam 41 rotates at a constant speed, the rods 47 and 48 reciprocate at a constant speed with a phase difference of 180 mm. In this embodiment as well, the rod constitutes a positive cam that does not move, and a compression spring for pressure contact is not required.

する効果がある。As explained above, this invention connects two followers with a phase difference of 180 degrees to a known constant velocity reciprocating cam,
By using a double constant velocity reciprocating cam, when one threshold is used for a fluid pump, there is an effect that pulsating flow is smoothed and a stable flow rate of fluid can be supplied. Also, with this invention,
Since the load on the discharge stroke of the pump becomes uniform, there is no need to waste money in determining the power source according to the maximum load, and there is an effect of improving operational efficiency. Furthermore, the present invention eliminates the need for an accumulator that absorbs fluctuations in the discharge pressure of conventional pumps, thereby improving the reliability of the pump system.
