ANORDING FOER STYRNING AV GENOMSTROEMNING AV ETT HYDRAULISKT TRYCKMEDIUM, SPECIELLT FOER BRAENSLEINSPRUTNING AV EN KOLVFOERBRAENNINGSMOTOR

摘要

The device has a valve housing (20) which contains an axially movable valve spindle (26) which forms a spool (27). The valve housing has at least one feed passage (21), connected to a source of pressure medium, at least one passage (22) connected to a piston (35'), and at least one drain passage (23). The spool (27) connects the passage (22) connected to the piston (35') either to the feed passage (21) or the drain passage (23). The valve spindle (26) is connected to a coil former (9) onto which is wound a driving coil (8) supplied with electric current. This driving coil is arranged in an air gap (7) which is located between the two magnet poles (5', 6) of a magnet (2) and through which the permanent magnetic field passes. IMAGE
