Generally, a hydraulic pressure vessel serves as a supply and/or discharge for a pressure medium in a hydraulic system. Such hydraulic pressure vessels are used, for example, in conjunction with hydraulic load cylinders to balance volume changes in a hydraulic system or to supply or remove excess pressure medium for short periods of time. Inside the storage vessel of the hydraulic pressure vessel is a bag made of rubber or man-made material filled with gas and pre-pressurized, which creates the vessel pressure; A return valve is provided for supplying and discharging pressure medium.

43−13912号公報参照）。 Conventionally, in order to control the opening and closing of the return valve, the return valve is constructed as a solenoid valve, and the valve body is opened and closed by the electromagnetic force of an electromagnetic coil acting on the valve shaft, or the valve shaft of the return valve is slid inside a cylinder. The valve body was opened and closed by the operation of a switching valve in a circuit that was equipped with a piston and communicated between the cylinder and an external hydraulic tank.
(See Publication No. 43-13912).

う問題があつた。 However, as mentioned above, when using a solenoid valve, the return valve is located only at the extreme positions between the open and closed positions, making it impossible to finely adjust the opening degree of the return valve. Since this is determined by the capacity of the valve, there is a problem in that when the capacity is large, a large electromagnetic force is required to open and close the valve body, making the solenoid valve mechanism large. In addition, when opening and closing the return valve by controlling the flow of the pressure medium in the circuit by communicating the hydraulic pressure means provided externally with the return valve in a circuit, the pressure medium in the circuit has a large capacity and the circuit configuration becomes expensive. There was a problem with becoming.

As described above, the conventional return valve for a hydraulic pressure vessel has a problem in that the electromagnetic valve or hydraulic means for controlling the opening and closing of the valve body has a large capacity, resulting in high cost. An object of the present invention is to provide a hydraulic pressure vessel which solves the problems of the prior art, makes the return valve control mechanism compact, and in particular reduces the pressure medium capacity of the hydraulic means and improves the responsiveness of the return valve. It provides:

To achieve the above object, the present invention provides a valve block incorporating a return valve with a servo valve directly connected to the cylinder chamber of the return valve, and further includes a spring means in the cylinder chamber for biasing the return valve in the opening direction. The pressure medium in the hydraulic means including the servo valve is reduced in volume and the response of the return valve is increased.

If the servo valve is provided directly in the valve block, the pressure medium supply circuit of the hydraulic means connecting the servo valve and the cylinder chamber of the return valve can be shortened, and the volume of pressure medium can be reduced. In addition, the spring means provided in the cylinder chamber of the return valve biases the return valve in the opening direction, and the opening/closing control of the return valve is made responsive by simply sending a small flow of pressure medium from the servo valve to the cylinder chamber. can do well.
以下、本発明を図面に示す実施例に基づいて説

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.
貯蔵容器１は容器２とガスで満された貯蔵袋３
とからなる。貯蔵袋３内の圧力ＰGASと貯蔵容器
１の中にある圧力媒体の圧力ＰO¨Lは同じである。 The storage container 1 consists of a container 2 and a storage bag 3 filled with gas.
It consists of. The pressure P GAS in the storage bag 3 and the pressure P O ¨L of the pressure medium in the storage container 1 are the same.
弁ブロツク５の中に戻り弁１０が備えられてい

Since a small force is required to move the movable piston 13 and the return valve 10, the servo valve 18 may also be small enough to balance this force.
シリンダチヤンバ１５の中にはばね手段として
ばね１９が配設されている。 A spring 19 is arranged in the cylinder chamber 15 as a spring means.
このばね１９は可動ピストン１３に作用し、そ

加える。この力は、貯蔵容器１の中で弁皿１１に
加わる力とは逆向きである。 This spring 19 acts on the movable piston 13 and exerts a force on the return valve 10 in the direction that it opens. This force is opposite to the force exerted on the valve plate 11 within the storage container 1.
ばね力と貯蔵容器内圧力とは一致させることが
できるので、弁１０を開くためにはわずかな変位
力を可動ピストン１３に加えればよい。このため
にこの貯蔵容器１は特に迅速に完全に開口した位
置に持ちきたすことができる。 Since the spring force and the pressure inside the reservoir can be matched, a small displacement force only needs to be applied to the movable piston 13 in order to open the valve 10. This allows the storage container 1 to be brought into the fully open position particularly quickly.

自動的に再び閉じる。 In order to open the storage container 1, the cylinder chamber 15 must be filled with pressure medium via the servo valve 18 and the pressure medium channel 17. At the same time, the pressure medium present in the cylinder chamber is discharged through the flow channel 16. In this way, the movable piston 13 with the valve stem 12 moves upwards. The valve plate 11 is moved up from the valve seat 21 and the return valve 10 and storage container 1 are opened. The pressure medium present in the storage vessel 1 reaches the load side through pressure medium discharge channels 22, 23. When the storage container 1 is empty, the return valve 10 is automatically closed again by the storage bag 3.
