A Leading Producer of Mobile Hydraulic Cranes

The present invention relates to an hydraulic valves, which inter alia, can be used as a completely novel type of blocking valve or so-called locking- valve. Such valves find use in hydraulic systems and are intended to block hydraulic lines passing to and from hydraulic motors. Such valves may also be used for the primary purpose of eliminating so-called load creep, which occurs in various types of hydraulic piston-cylinder devices or rams when under load and which, more specifically, means that any load whatsoever held by an hydraulic piston-cylinder device will be slowly lowered due to internal leakage of hydraulic medium in the hydraulic system, and particularly in operating valves present in the system.
