本発明は車両（４輪車、２輪車等）の停車時においてブ
レーキ液圧を保持するだめのバルブ装置（以下オートス
トップバルブと称する）に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a valve device (hereinafter referred to as an auto-stop valve) that maintains brake fluid pressure when a vehicle (four-wheeled vehicle, two-wheeled vehicle, etc.) is stopped.

る。It is better to keep the vehicle stopped until it starts moving forward (or backward) to prevent the vehicle from moving unexpectedly, but in normal driving operations, is it only necessary to release the brake pedal from the road after the vehicle has stopped? A parking brake mechanism is often used, such as when riding on a slope or on a slope.
しかしこのような操作は繁雑であるし、坂道等以外では
パーキングブレーキを使用しないことが多いためＫ、停

を提供するものである。Therefore, in view of these various points, in the present invention, after the vehicle is stopped by performing a braking operation of a vehicle having a hydraulic braking mechanism, that is, a brake operation, the next forward (or backward) movement of the vehicle is stopped. Until an operation is performed, such as engaging the clutch and starting the vehicle, the wheel is mechanically and automatically removed from the mask cylinder in order to maintain the wheel cylinder fluid pressure (brake fluid pressure) in the brake device. An electromagnetically actuated pulp (referred to as auto-stop pulp) is installed in the hydraulic path connecting the cylinders.
This auto-stop pulp is configured to maintain and continue to maintain the brake fluid pressure in the foil cylinder from a vehicle stop operation (brake operation) to the next vehicle start operation.

プパルプの提供を目的とするものである。In other words, the present invention includes a cylindrical body having a radial liquid passage opened on the inner circumferential surface of the cylinder, a piston to which a circumferential seal member is attached to the inner circumferential surface of the cylinder of the cylindrical body, and a solenoid. The armature that is moved by the excitation of the solenoid is provided with an armature that electromagnetically generates a moving force by excitation, and the armature that moves by the excitation of the solenoid moves the man/output liquid chamber which is normally communicated by the radial liquid passage. The object of the present invention is to provide an auto-stop pulp configured to shut off by moving a sealing member, and to continue the shut-off state of the input and output liquid chambers by energizing the solenoid from the stop of the vehicle until the next start. be.

バイパス経路を設けてもよい。In addition, in order to ensure that the brake fluid pressure is re-pressurized when the input/output fluid chambers are shut off, the circumferential seal member described above must have a unidirectional structure that allows fluid flow from the input fluid chamber to the output fluid chamber. A bypass path may be provided, either by a sealing member (eg, a piston cup) or by a check valve that allows fluid flow in the same direction.

が段付太径に形成されている。In FIG. 1, 1.2 is a pair of sleeve members screwed together, one of which 1 is made of a ferromagnetic material,
It functions as a pole iron core that forms part of a magnetic circuit generated by a solenoid, which will be described later. The other end 2 is not a magnetic material, and has an armature 3 built-in and housed in its inner cylindrical portion.0 The end side of the sleeve member 1 opposite to the screwing side with the sleeve member 2 has a slight step in both the inner and outer diameters. It is formed with a large diameter, and a plug 4 is screwed and fixed to the open end thereof. Further, the end of the sleeve member 2 on the side opposite to the screwing part is formed to have a stepped outer diameter and a large diameter.

る。A housing case 6 in which the solenoid 5 is wound and housed is fitted and fixed on the small diameter outer periphery located between the large diameter portions at both ends of the threadedly connected sleeve member 1.2. When this solenoid 5 is excited by a control circuit (not shown), it applies a magnetic field so that the armature 3 housed in the sleeve member 2 approaches the ball iron core 1 (moves it to the left in the figure). It is something that causes

A plurality of internal and external liquid passages 4b are provided.

部に取着している。A piston 7 is fitted into the inner cylindrical portion of the circumferential wall 4a, and a circumferential seal member 8 snaps onto the inner cylindrical surface of the circumferential wall 4a.
A piston cup (in this example, a piston cup) is attached to a part of the outer periphery of the piston 7.

ることになる。Reference numeral 9 denotes a set spring that applies a spring force to lock the piston 7 to the armature 3. Normally, the spring force of the cent spring 9 causes the seal member 8 to move further than the opening position of the liquid passage 4b. It is configured to be located on the tip side of the peripheral wall portion 4. Therefore, in this state, the liquid chamber inside the liquid passage 4b (referred to as the output liquid chamber B) is in communication with the liquid chamber outside the liquid passage 4b (referred to as the input liquid chamber A), and the piston 7 is Move to the left and seal member 8
When the liquid passes through the opening of the liquid passage 4b, the communication is interrupted.

次にその作動について説明する。Note that the output liquid chamber B is communicated with a brake device via a port 10, and the input liquid chamber A is communicated with a mask cylinder via a port 11. Further, the outer portion of the peripheral wall portion 4 is
It goes without saying that the sleeve member 1.2 is in communication with all of the inner cylindrical portion of the sleeve member 1.2 except for the output liquid chamber B within the peripheral wall portion 4.Next, its operation will be explained.

択できる。In this example, the solenoid 5 is energized in response to a predetermined electrical command several seconds after the vehicle has stopped due to a vehicle braking control operation, for example, until the next vehicle starting (or reversing) operation, such as an operation to connect a clutch. The solenoid is controlled to continue energizing, but in the case of so-called automatic vehicles, the solenoid may be de-energized by pressing the accelerator pedal; in other words, the solenoid is controlled to continue energizing before the manual brake operation is released. It is sufficient to set the control so that the hydraulic pressure is maintained and the next vehicle starting operation is not hindered, and various suitable controls can be selected depending on the nature and model of the vehicle.

リンダに伝えられる。Here, in the initial stage when the brake fluid pressure is transmitted through the auto stop valve in the illustrated state, the hydraulic pressure in the axial direction acts in equilibrium on the armature 3, so no moving force acts on the piston 7, and therefore the input/output fluid Communication between chambers A and H is maintained, and brake fluid pressure is transmitted directly from the mask cylinder to the foil cylinder.

。In this state, when the vehicle speed decreases and the solenoid 5 is energized after stopping, the armature 3 is attracted to the left in the figure, and the piston 7 is moved to enter the peripheral wall 4. At the point when the liquid passage member 8 passes through the opening of the liquid passage 4b, the communication between the person/output liquid chambers A and B is cut off.
この後、ソレノイド５の励磁力によってアマチュア３が
励磁移動されている状態が維持される限り、出力液室Ｂ

ことに々る。After this, as long as the armature 3 is maintained in a state where it is excited and moved by the excitation force of the solenoid 5, the output liquid chamber B
The brake fluid chamber within the brake system is often maintained.

In order to allow liquid flow from the output liquid chamber BK, it has a feature of providing a bypass path 13 with a built-in check valve 12,
The rest of the structure is the same as that of the previous embodiment, so common members are given the same reference numerals.

しているのである。The function of the bypass path 130 is the same as that of the piston-mounted seal member 8 described above, and in short, the movement of the piston/7 causes the input/output liquid chamber A
When the input liquid chamber A is pressurized again while the communication between the two chambers B is cut off, this liquid pressure is transmitted to the output liquid chamber B.
