摘要： PURPOSE: To provide a combined valve device which has a relief function, a function of short circuit escape in neutral position and a fluid replenishing valve function, by providing a plurality of springs to energize and hold valves in a balancing elastic manner.
CONSTITUTION: When the discharge quantity and discharge pressure of a pump PE increase, a pressure difference Pa-Pc also increase. When the pressure Pb of a right chamber 11b has become almost equal to pressure Pa, a valve 20 is moved leftward in accordance with the difference of the right and lift pushing forces to the valve 20 and a central valve 30 to close a port 12a. The closure of the port 12a by the valve 20 functions as a check valve for a short circuit. When the negative pressure on a suction side increases, the pressure Pb' of the right chamber 11b falls and the leftward pushing force to the valve 20 and the central valve 30 decreases. consequently, pressure Pc' of replenished liquid from a replenishing pump PA is received by a left chamber 11a' to move the valve 20 rightward to open a port 12a'. A relief function is fulfilled by the rightward movement of a valve 43 as an ordinary short circuit is formed.

摘要翻译：目的：通过提供多个弹簧来以平衡弹性方式激励和保持阀，以提供具有释放功能，中性位置的短路逃逸功能和流体补充阀功能的组合阀装置。构成：当泵PE的排出量和排出压力增加时，压力差Pa-Pc也增加。当右室11b的压力Pb变得几乎等于压力Pa时，阀20根据向阀20的右升压推力的差异和中心阀30关闭端口12a向左移动。通过阀门20关闭端口12a用作短路的止回阀。当吸入侧的负压增加时，右室11b的压力Pb'下降，向阀20和中心阀30的向左推压减小。因此，来自补充泵PA的补充液体的压力Pc'被左室11a'接收，向右移动阀门20以打开端口12a'。当形成普通的短路时，通过阀43的向右运动来实现释放功能。

摘要： PURPOSE: To obtain a valve having both check valve function and neutral valve function by slidably providing a valve body, of which valve head is kept apart from a valve seat by a predetermined distance by means of power balance of two springs, in a valve hole communicating with a forced-in circuit and a main circuit.
CONSTITUTION: A block element 10 is equipped with a forced side through hole 11 and a main circuit side through hole 12. In a bottom part 15 of a cylinder hole 14 bored toward the forced side through hole 11 from an end face 13, a through hole 16 is bored to communicate with the forced side through hole 11, and its angular part 17 becomes a valve seat. Also the cylinder hole 14 communicates with the through hole 12 via a chamber 18, and at the same time a sleeve element 20, wherein a valve hole 22 is formed, is inserted into the cylinder hole 14. A valve body 26 equipped with a valve head 25, which can abut on and engage with a valve seat 17, is slidably inserted. And the valve body 26 has a valve head 25 separated from a valve seat 17 by a set distance by means of a balanced power of a first spring 28 pressing toward the valve seat and a second spring 29 pressing the valve body 26 against the first spring 28.
