  • Hydraulic trip unit for a valve unit in a prime mover plant, especially for a fast-acting shut-off valve of a turbine plant
    Patent number: 8662106
    Abstract: A hydraulic trip unit for a valve unit in a prime mover plant is described, with monitoring passages which are grouped together in a hydraulic block and interconnected forming a 2 out of 3 circuit, of which each monitoring passage is provided with a solenoid valve unit, with a power oil line connection which is provided on the hydraulic block and from which an emergency oil passage and an auxiliary emergency oil passage extend inside the hydraulic block, of which the emergency oil passage can be connected to the valve unit and the auxiliary emergency oil passage is connected via connecting lines to a solenoid valve unit in each case, wherein a first connecting line feeds a first and third solenoid valve unit, a second connecting line feeds the second and a first solenoid valve unit, and a third connecting line feeds the third and second solenoid valve unit.
