In recent years, with the rapid growth of the economy and the development of ground-breaking industries, various automobiles have become indispensable means of transportation and have made a great contribution. Traffic accidents are also on the rise, and the current situation is developing into a major social problem. Research has recently begun in Japan and other countries on a so-called air bag safety device that instantly inflates an air bag using high-pressure air during a car collision to cushion and protect the driver from the shock. It is being done. In this type of automobile safety device, a fluid valve is required that can be opened instantaneously and appropriately in the event of a collision, rear-end collision, contact accident, etc. of the automobile. However, conventionally, this type of fluid valve has been of the solenoid valve type, which senses the impact of a car collision and operates the solenoid valve using an electrical signal, or a computer has been introduced in response to various types of collisions. Generally, electronic valve devices are used that issue an appropriate input signal and open the valve in response to the input signal, but all conventional valve devices of this type do not respond to the input signal of a collision. Although efforts have been made to respond quickly, a slight delay in electrical operation is unavoidable.
Additionally, the mechanism of the valve itself has problems such as operating resistance, making it difficult to perform its functions quickly and smoothly.Furthermore, the mounting position of the impact sensing mechanism may vary depending on the vehicle type, collision conditions, etc. This involves a complicated problem, and it is extremely difficult to open the valve instantly and smoothly in the event of an automobile collision, which is a major bottleneck for conventional automobile safety devices of this type. .

Further, the ball valve body 15 always closes the valve seat 14 by fluid pressure, and the protruding valve rod 13 that pushes the ball valve body 15 to open the valve is slidably inserted into the shaft hole 12c of the valve housing 12. Since the valve part 11 is used, it has the advantage of extremely sharp and smooth operation, simple structure, less failure, and easy maintenance.
Since the protruding valve rod 13 is positioned on the same axis as the hammer rod body 2 with a play interval, the hammer rod body 2 is moved by inertia to the ball valve body 15 through the valve rod 13 in the event of a collision. This applies an impact load, and this impact load (impact force) is applied to the valve portion 11 during a car collision.
Since it acts like a counterpunch against the rapid impulse force of the ball valve body 15, it has the effect of bringing about an instantaneous valve function of the ball valve body 15 and obtaining a sharp valve opening action. Since a stopper pin 8 is provided to prevent the moved rod hammer body 2 from returning to its original position, stable and reliable opening of the valve is guaranteed at all times even in the event of any multilateral impact. Further, since the locking pressure of the rod hammer body 2 in the fixed cylinder body 1 is adjustable by a locking device attached to the fixed cylinder body 1, the rod hammer body 2
Adjust the locking pressure level as necessary to ensure that the locking force is activated only in the event of a collision, etc.
For example, it can be adjusted so that it does not operate when the brakes are applied suddenly. Also, for example,
When a car according to US regulations collides at a speed of 30km/h or more, the rod hammer body 2 releases the lock against the locking pressure, and hits the valve rod 13 with even stronger force, causing the ball valve body 15 If the locking pressure described above is set in advance as the locking pressure of the rod hammer body 2 so that the valve can be pushed open, in the event of a collision at a speed of 30 km/h or less, the rod hammer body 2 will push the valve open. In other words, if the locking pressure for pushing the ball valve body 15 to open the valve according to the speed of the car at the time of a collision is determined in advance by a test, the setting of the valve opening function can be adjusted. It has the effect of allowing you to do it freely. The situation after the rod hammer body 2 is released from the lock by the ball 5 of the locking device is as follows. The unlatched rod hammer body 2 loses its axial restraining force and is accelerated by the inertia force generated by the deceleration movement of the fixed cylinder body 1, reducing the play distance with the valve rod 13. runs and collides with the protruding valve rod 13, and the protruding valve rod 13 collides with the ball valve body 1.
5 to open the valve part 11. Although a car collision is an event that occurs over a very short period of time, the deceleration movement time of the fixed cylinder body 1 is longer than the above-mentioned movement time of the rod hammer body 2.

In addition, the fixed cylinder 1 of the fluid valve of the present invention itself is an impact sensing part, and if it is integrally fixed to the car body, it can always operate sharply no matter where it is installed, and is highly effective for systematic control of this type of car safety device. It has excellent effects such as being stable and reliable, and can be provided at low cost. Furthermore, even if the ball valve body 15 is instantly opened by hitting the valve rod 13 with the hammer body 2, if there is no stopper device to prevent the rod hammer body 2 from restoring movement, the ball valve body 15 once opened will be , the valve would instantly close again due to high fluid pressure, and high pressure fluid would no longer be supplied to the air bag. However, in this invention, a mechanism is installed to prevent the moved rod hammer body 2 from returning to its original position. Since the stopper pin device is provided, the ball valve body 15 is kept open, and the high pressure fluid can be smoothly supplied to the air bag without interruption, which guarantees a high level of safety for the air bag function. It has a huge effect. In other words, since a stopper device is provided to continuously maintain the valve open, the air bag system will not function properly under any operating conditions or under any accident. This has the tremendous effect of making it possible to create a trowel that always operates reliably, ensuring 100% operational reliability of the airbag system.
