Pilot valve, preferably to be applied in hydraulic tools, preferably rescue tools, executing the protective function for executing system against the pressure drop in the case of sudden drop of hydraulic liquid pressure

摘要

control valve, especially for use in hydraulic rescue tools, especially with security function implementing system before pressure loss in case of sudden drop in the pressure of hydraulic fluid, containing the control unit, to which ego is affixed part connection is suchthat part of the connection (2) has at least two threaded attachment holes (11, 12) to be screwed ends high-pressure hydraulic hoses, and the body (1) in part opposite in relation to the part of connectivity (2) is equipped with a collar (42) on which the m is positioned nut (8), connecting valve mechanism of implementing module (tool).on the body are positioned at least two slip rings (9, 10) between which is positioned manetka (44), a striker, dociskana position resting springs, placed in the space (1).the ends of the springs are based on a fixed body (1) and a manetki (44), and placed on the opposite in relation to the attachment holes (11, 12) selected the control unit (1) is placed the pilot valve (3), in which is embedded a zipper ( 4).hole (11) is established przyu0142u0105czeniowym channel dopu0142ywowy who within the valve body (3) through another channel and is branched in the peripheral).
