い不都合を伴う。Conventionally, this type of device has a plunger 0, which has a vertical oil hole a inside and a free ball type or other check valve at its lower end, as shown in the first diagram, and is lowered into a plunger body d on the outer periphery. It is provided so that it can be elastically pushed upward by a side spring e, and pressure oil can be freely introduced into this through a guide hole f on the side thereof, so that the gap created in the four arms g can be automatically corrected. However, in that case, the lower oil chamber of the plunger C formed at the bottom of the plunger body d generally has a relatively large volume.
In some cases, due to the elasticity of the hydraulic pressure itself in the chamber or the influence of air bubbles contained separately, it has a spring-like property as a whole,
As a result, the plunger 0 tends to sink when it is depressed downward, increasing the damage caused by the plunger 0. Furthermore, it tends to resonate in the high rotational range of the engine, making it difficult to obtain good operation as a whole.

した。In the drawing, +1) indicates a plunger, and the plunger (1)
is a free-ball type check valve (3) which is equipped with an oil hole (2) in the vertical direction inside, and is composed of a pole (3&) facing the pole (3&) at the lower end thereof and a cage (3b) supporting the ball (3a). ). The plunger Il+ is accommodated in the plunger body (4) on the outer periphery by being resiliently pushed upward by the lower spring (5), and pressure oil can be freely introduced into it through the guide hole (6) on the side surface. . In this case, (5) ill,
According to the present invention, the oil chamber (6) is comprised of a coil spring housed in a lower oil chamber (7) of the plunger (1) formed at the bottom of the plunger body (4). A spacer (8) is provided to protrude within the portion (7) to reduce the volume within the portion (7). More specifically, the spacer (8) is of a type that extends into the internal space of the coil spring (5) described above at the bottom of the oil chamber (inside the oil chamber), and in this case, the spacer (8) has the cage (3b) and the cage (3b) described above on its top surface. A space of a predetermined height exists between the cages (3
b) and the upper surface of the spacer screen (8), some gap was left to prevent damage to the cage (3b).

成させることもｎＪ能である。To explain further, the spacer (8) is prepared in advance separately from the plunger body (4) as shown in the second figure, and is placed on the bottom surface inside the body (4), and is placed on the outer periphery of the upper end. The spacer (8) is sandwiched between the spring (5) and the bottom surface of the seventh flange (8a) for stability, or as shown in the figure, the spacer (8) The existing concave groove (8b) is located and the groove (8b) corresponding to this is provided.
5) so that the lower ends of the spacer (8) and the spring (5) are fitted and supported, or the core portion is made a predetermined tapered surface instead of the concave groove (8b), and the spacer (8) and the spring (5) are separated in advance. It can be assembled and incorporated into the part (6). Furthermore, the spacer (8)
For example, it is also possible to form it integrally with the main body (6) in advance as shown in the third figure.

を有する。In this way, according to the present invention, the volume of the oil chamber on the lower side of the plunger is reduced by a spacer protruding from the oil chamber, and this is a spring that cooperates with a spring that relatively elastically repels the granger upward. It has the effect that it can be fixed stably in the shape of a seat, and can be advantageously used to improve assemblability.
