分に満足しない。(Background Art) In Japanese Patent Application No. 57-167618, which the applicant has filed and which has not yet been published, a rotor (7 and A vane (71) fitted into the rotor (7) so as to be removable and pivotally supported by a pivot part (A) provided in the inner cavity (A) of the housing (10) and a rotor (71) The vane (7) has a ring 0Q surrounding it and the entire housing bore (7).
and the outer periphery of the ring 151, there is another chamber ufi, (separated from the 171/
At the outer periphery of the ring, so as to form a pressure chamber Hk)
- Axial grooves opening into the inner cavity of the housing (54 protrusions (541), 55 protrusions (561), elastic members (63) installed at the bottom of each groove, elastic members of the valley grooves) A variable discharge amount vane pump (1) having seal pins (60 bars 61, 62) is disclosed.The elastic member (63) is exemplified by synthetic rubber and a plate spring (not shown). However, in order to maintain its actual function, the elastic member (63) must be able to fit into small spaces where it is not possible to increase its stiffness, and has a considerable amount of deflection and complete elastic recovery against repeated stress. However, the above-mentioned synthetic rubbers lack the amount of deflection and restoring properties, and leaf springs are difficult to design, are weak in strength, easily break, and lack elastic restoring power. Are there any functions that are necessary for an elastic member, such as not becoming obsolete?
Apart from the fact that it fits into a small space, neither i+ nor n is fully satisfied.

02) has been proposed. This spring is an improvement over the synthetic rubber or leaf spring described above, and although it fulfills the various functions mentioned above, it is relatively expensive and requires some experience to assemble. Problems arose, such as not being able to do this quickly, and furthermore, when the filigree springs were stored, the filigree springs became entangled with each other, making it time consuming to remove them.

なった。Therefore, in the present invention, the elastic member has a plate-shaped base 81S made of spring steel whose outer periphery is approximately similar to the outer periphery of the bottom surface of the groove, and a plate-shaped base 81S made of spring steel, and a part that is punched out from the base or connected to the base with one end thereof. This variable discharge amount vane pump is characterized by being a plate spring consisting of a continuous tongue portion with the other end bent upward. With this structure, the plate spring can be made by simply punching out a spring steel plate using a press, so it is relatively inexpensive, and when pressed, the tightness is the same as the thickness of the plate base. The ring has a large free length, a low height and a small space in the groove, and has sufficient deflection and strong complete elastic restoring force, so it can reduce the relative displacement between the ring and the housing bore. Regardless of the size, the seal pin is always pressed appropriately against the housing inner cavity to complete the sealing function.

同志がからむことがないので保管が容易となった。Moreover, the assembly is performed with the continuous part at the back of the groove in the axial direction (
54, 55, 56), and the sides of the grooves act as guides to guide the plate-like base and prevent it from swinging up, down, left or right, making assembly very easy. Also, the plate springs will not get entangled with each other during storage. This makes storage easier.

shows the The plate spring (100) has a rectangular spring steel plate base (10) whose outer circumference is approximately similar to the bottom outer circumference of the groove (54, 55, 56) shown in FIG. It consists of a tongue (103) which is continuous with one end of the base and the other end (10) is bent upward.The tip (105) of the tongue (103) is the fourth
In the figure, it forms three sides of a rectangle, but as shown in FIG. Preferably, the plate spring (11) shown in FIG.
0), the continuous part (104ri) has a gently warped rising curve shape, so that when it is pressed from above as seen in the figure, the corner n-curve v part, that is, the continuous part ( 104') to prevent stress from concentrating on the continuous part 041) in Fig. 5.
As shown in the figure, when it is pressed from above, the stress applied to the n-bent v part is dispersed. ”
It is designed to provide spring force and improve durability.

せる。Plate spring (10s (or 110) f) When attaching the l material to the axial loads (54, 55, 56) shown in Fig. 1, first insert the seal pins (60, 61, 62) in Fig. 9. Insert from direction C shown by. Therefore, the side surface of the groove (5) serves as a guide to guide the plate-like base plate, and since the tongue (103) and the seal pin (62) come into sliding contact, it moves vertically and horizontally. It has become very easy to assemble.Also, it has become easier to store the plate spring (10s010) because it does not get tangled when stored, and it does not take time to remove it by combing. Crafted springs can be easily punched out of spring steel plates, so even though they are relatively cheap, the thickness of the spring is the same as the plate thickness, and the effective stroke is large, meaning the free length can be large, so it can be used in narrow spaces. The sealing pin is always pressed against the housing inner cavity and has a perfect elasticity to perform a proper suppressing sealing function.
