摘要： The present invention describes a multi-functional hydraulic assembly for driving hydraulic fools with the aim of fulfilling as many requirements as possible for a variety of system applications. This is realized, firstly, by a high-performance cooling and filtering concept, secondly, by modular cascadability of the motor and the electronics, or also the option to be able to attach any number of auxiliary reservoirs via suction lines or communicating systems. To meet the requirements of the industry in terms of data management, access and currentness, it is possible to control and to update the assembly and to bidirectionally exchange data via external central servers or via a cloud. Program data and/or process data and/or system data of the hydraulic assembly is by means of an online portal as a cloud service stored and analyzed for process evaluation and provided to an authorized group of individuals for download or via a web browser. A further cloud service informs the user and clients in automated form when maintenance of the assembly or the system is pending or necessary. Moreover, it is possible via the cloud to integrate all employed system accessories for the inclusion of maintenance intervals, thus creating a flexible overall system and ensuring the multifunctional use of the hydraulic assembly in the system network.

A dynamic seal can be disposed on a land of a valve element. A supply passage can be in communication between the control chamber and a tank and can include a check valve. A relief valve can be disposed between the check valve and the control chamber. A pilot pump and another relief valve may be disposed upstream of the check valve. The relief valve downstream of the check valve can have a higher pressure limit than the downstream one. A pressure sensor may be disposed between the check valve and the control chamber and used to warn the operator of a high pressure in the control chamber.
