Definitions
- the invention relates to an electromagnetic drive, in particular for low-performance control of fluidic control devices such as Small valves and the like.
- This object is achieved according to the invention by an electromagnetic drive reached, a magnetic core surrounded by a coil and a movable armature, the armature having a Reset element is combined into a component.
- the anchor is flat Anchor plate formed and an air gap on an end face of the Magnetic core arranged opposite.
- the anchor plate held and guided by the return element.
- an elastic membrane with a flat surface is suitable as a reset element connected to the anchor plate and clamped on its outer edge.
- the magnetic core is from surrounded by a cup-shaped yoke and has one opposite the anchor radially outward collar on, with the yoke the air gap limited.
- the coil be wound directly onto the magnetic core. It turns out as advantageous if the magnetic core through a cylindrical core body is formed, which has a flange-like at each axial end Wearing collar. There is a simple design if that of the Collar of the magnetic core facing away from the air gap fits into a recess can be used at the bottom of the yoke.
- a flat magnetic flux piece can be arranged to the anchor plate.
- the electromagnetic drive according to the invention in a solenoid valve can reduce the number of components required can be reduced that the membrane opposite a valve seat is arranged and acts directly as a closing element.
- the magnetic flux piece is annular and surrounds the valve seat coaxial.
- valve connection formed as a channel coaxially penetrating the magnetic core and the Valve seat arranged coaxially to the magnetic core.
- Another improvement the device is achieved by means of the anchor plate the membrane is held and guided so that it wobbles for automatic alignment on the valve seat.
- an electromagnetic drive which in a solenoid valve is used.
- a pot-shaped yoke 1 is accommodated in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 in the lower part 8 one two-part housing, a pot-shaped yoke 1 is accommodated.
- an electromagnet is accommodated in the yoke 1 and has a magnetic core 4 and comprises a coil 7 wound directly on the core 4.
- the core 4 consists of a cylindrical core and an upper and a lower flange-like collar 5 and 10 together on the upper and lower axial end of the core body are formed and extend radially outward.
- the yoke 1 points in its Bottom section a recess into which the lower collar 10 of the Magnetic core is used appropriately.
- a flat, movable anchor plate 2 is arranged in the chamber 11, which has the same diameter as the yoke 1.
- the anchor plate 2 is in a first switching position of the valve, in which the Electromagnet is not activated by the yoke 1 through a gap 12 separated by the lower collar next to the yoke 1 by the upper collar 5 of the magnetic core 4 is limited.
- the anchor plate 2 is with a Membrane 3 trained reset element coupled to her Outer edge is clamped.
- the membrane 3 is flat with the Anchor plate 2 connected so that anchor plate 2 and membrane 3 are one component form. Characterized in that the anchor plate 2 firmly with the membrane 3rd connected, it is held and guided in its movements.
- a lower valve connection R passes through the lower housing part 8 and the magnetic core 4 coaxially and is connected to the gap 12.
- An upper valve port P is coaxial with the lower one Valve connection R and vertically through the upper housing part 9 and a valve seat 13 integrally formed thereon.
- the valve seat 13 protrudes into the chamber 11 and is arranged coaxially to the magnetic core 4.
- the membrane 3 is arranged opposite the valve seat 13 and is in the first switching position of the valve on the valve seat 13, so that thereby the mouth of the port P in the chamber 11th is closed.
- the anchor plate 2 is so by means of the membrane 3 held and guided that they wobble to self Alignment on the valve seat 13 can perform.
- Valve outlet A which is arranged laterally offset to the port P. and is next to the valve seat 13 in connection with the chamber 11.
- valve seat 13 coaxially surrounds and on an inner wall of the upper housing part 9 is present.
- the valve connection is there P via the air gap 12 and the chamber 11 in connection with the outlet A, while the mouth of the port P into the chamber 11 through the Membrane 3 is closed, i.e. the membrane 3 acts directly as Closing element.
- the armature plate is activated by activating the electromagnet 2 moved together with the membrane 3 formed thereon and closes the mouth of port R, whereas the mouth of the Port P is released.
- the port P is now over the chamber 11 in connection with the outlet A.
