摘要： The purpose of the invention is to create an electromagnetic valve for redirecting of hydraulic media which is, depending on each received signal, used to control operation of at least one appliance integrated into each disposable high-pressure hydraulic circuit with nominal pressure between 50 and at least 150 bar, wherein just water, optionally combined with environmental friendly anti-freezing additives should be used as a hydraulic media in such hydraulic circuit, in which the operating pressure should be at minimum 50 bar up to at least approximately 250 bar. Said electromagnetic valve comprising a housing (1), in which a chamber (3) is available, which is intended to receive a redirecting member (2) and each hydraulic media i.e. the water in this particular valve. Said housing (1) is furnished with at least three connecting openings (A, B, P, T), which are arranged corresponding to each desired function of the valve as such, as well as with an electromagnet (4, 4'), which is arranged in/on said housing (1) and is adapted to cooperate with said redirecting member (2). In accordance with the invention, both the housing (1) at least in the area of the internal sealing surface (30) of the chamber (3) with diameter (D 3 ), and also said redirecting member (2) at least of its external hydraulic sealing surface (20) with diameter (D 2 ), consist of quenched steel, wherein the gap (C) there-between, namely the half difference between the characteristic diameter (D 3 ) of the sealing surface (30) of the chamber (3) and the characteristic diameter (D 2 ) of the sealing surface (20) of the redirecting member (2) should be between 1 μm and to 5 μηι at maximum.

摘要： In order to enable using water as a hydraulic liquid in a high-pressure piston pump for hydraulic circuits with nominal pressure more than 50 bar and up to at least 250 bar, on the one hand an area on the internal wall (10) of a cylindrical operating chamber (1), which cooperates with the external surface (20) of a piston (2) and is at least temporarily in contact therewith, consists of polyether-ether-ketone (PEEK), and on the other hand at least an area of the external surface (20) of said piston (20), which cooperates with said internal surface (10) of the operating chamber (1), consists of martensitic stainless steel. An eccentric (22) of a crank (21), which generates oscillating movement of the piston (2) along said cylindrical operating chamber (1), is offset relative to the longitudinal axis (100) of said operating chamber (1) at a predetermined distance (e) transversally with respect to said longitudinal axis (100), by which the crank (2) is at least during the most critical stage of the piston (2) stroke positioned at least approximately on said central axis (100) of the operating chamber (1).
