but it has an inductive magnetization due to the magnetic circuit when a current impulse of suitable polarity that between the two pole shoes 27 generates a magnetic field opposite to the induced magnetic flux in the valve element 31 is applied to the contact shoes 25 the valve element 31 is shifted from the end position shown in fig2 into the opposite end position in which it blocks the passage from the inlet line 34 to the outlet line 37 and unblocks the passage to the outlet line 38 in such an end position a magnetic circuit analogous to the one described above is formed between the permanent magnet 36 and the left hand valve seat 32 and keeps the valve element 31 in the end position the valve body is shifted back into the end position shown in the figure by a current impulse of opposite polarity the solenoid valve is completed by an upper housing part 40 that is shown in fig3 in a perspective view on the lower part 1 but without the magnet coil and valve body like the lower part 1 the upper part 40 also has a first compartment 41 for the coil and a second.
