Abstract
Abstract An integrated multiple valve unit is provided as a module of hydraulic circuit components and for uniform pipe line geometry. The unit generally comprises a subplate upon the top surface of which are formed a plurality of valve assembly mounting seats in equally spaced apart relation, and a plurality of stacks each comprised of valve assemblies and a solenoid valve mounted on the subplate in the order named. Any of the valve assemblies which effect various functions may be selected and stacked, depending upon desired hydraulic circuit requirements. Each valve assembly seat is provided with a supply port, a discharge or return port and a pair of intake ports, that is the ports for connection with an actuator or the like, at the positions corresponding to the corresponding ports of the solenoid valve. At the undersurface of the subplate are formed a plurality of zigzag intake ports which are spaced apart from each other by a predetermined distance, for example, equal to one half of the spacing between the mounting seats, and intercommunicated with the corresponding intake ports in the mounting seats. A supply port and a discharge or return port of the subplate are intercommunicated with all of the supply and discharge ports in the mounting seats through a supply passage and a discharge passage, respectively.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
247 words
An integrated multiple valve unit, comprising a subplate having one side provided with a plurality of mounting seats spaced by a predetermined distance from one another and each formed with an individual supply port, an individual discharge port and individual intake ports, an other side provided with a plurality of zigzag intake ports spaced by a distance equal to one half of said predetermined distance in longitudinal and transverse direction of said subplate and communicating with said individual intake ports, a joint supply port communicating with all of said individual supply ports, and a joint discharge port communicating with all of said individual discharge ports; and a plurality of valve stacks each comprising a valve plate mounted on one of said valve seats and having a valve plate supply port, a valve plate discharge port and valve plate intake ports communicating with respective ports of said subplate at said one side thereof, a hydraulic valve assembly on said valve plate and communicating with respective ones of said valve plate ports, and a solenoid valve mounted on said valve assembly and communicating via the same with respective ones of said valve plate ports, said valve unit having said ports arranged in a configuration permitting the interposition of a device between said subplate and said valve assembly which includes a stop valve and a nonreturn valve assembly, whereby selected members of said valve assemblies can be isolated without the necessity to cut off the entire integrated multiple valve unit.
Claim 2
Dependent Claim
247 words
An integrated multiple valve unit, comprising a subplate having one side provided with a plurality of mounting seats spaced by a predetermined distance from one another and each formed with an individual supply port, an individual discharge port and individual intake ports, an other side provided with a plurality of zigzag intake ports spaced by a distance equal to one half of said predetermined distance in longitudinal and transverse direction of said subplate and communicating with said individual intake ports, a joint supply port communicating with all of said individual supply ports, and a joint discharge port communicating with all of said individual discharge ports; and a plurality of valve stacks each comprising a valve plate mounted on one of said valve seats and having a valve plate supply port, a valve plate discharge port and valve plate intake ports communicating with respective ports of said subplate at said one side thereof, a hydraulic valve assembly on said valve plate and communicating with respective ones of said valve plate ports, and a solenoid valve mounted on said valve assembly and communicating via the same with respective ones of said valve plate ports, said valve unit having said ports arranged in a configuration permitting the interposition of a device between said subplate and said valve assembly which includes a stop valve and a nonreturn valve assembly, whereby selected members of said valve assemblies can be isolated without the necessity to cut off the entire integrated multiple valve unit.

Claim 4
Dependent Claim
54 words
An integrated valve assembly as defined in claim 1, wherein each mounting seat is further provided with additional tapped holes; and said valve assemblies include a joint valve assembly which has cooperating tapped holes corresponding to said additional tapped holes, and a joint port intercommunicated with one of said supply, discharge and intake ports.
Claim 5
Dependent Claim
31 words
An integrated valve unit as defined in claim 1, wherein said valve assemblies include a valve assembly having a pair of valve assembly discharge ports and a passage intercommunicating the same.
Claim 6
Dependent Claim
