Definitions
- the invention relates to an actuating device, in particular with actuation by an electromagnet, according to the preamble of claim 1.
- an actuating device for an electrically actuated valve is known, with which, despite the use of components with usual tolerances of the basic air gap, an exactly predeterminable size can be obtained.
- a return plate as an adjustable part is held on a housing by a return spring.
- the actuating device contains a magnetic core as a fixed part.
- the return spring is held on a pin and the adjustable part is connected to the pin.
- the pen has a collar.
- the return spring is clamped between the collar and a spring resting on the adjustable part.
- the basic air gap can be varied by more or less deeply pressing in a suitable connection, for example the pin, in the adjustable part. The component tolerances can thus be easily compensated for.
- the valve characteristic curve cannot be changed. After determining the dimensions of the actuation device and the steering valve, the valve characteristic curve is finally established.
- the invention has for its object to design an actuating device such that an adjustment of the valve characteristic of a steering valve is possible after the assembly of the power steering.
- the actuating device characterized in claim 1 This object is achieved by the actuating device characterized in claim 1.
- the essence of the invention is that the adjustable collar allows the basic air gap to be set even after the actuating device has been installed, for example in an electro-hydraulic converter of a steering valve. This allows the valve characteristic to be set and a narrower tolerance band to be achieved on the steering valve. The valve characteristic can be placed in a specific, desired tolerance range.
- the adjustable collar can be formed in a simple manner by a nut which is adjustable via a thread arranged on the pin.
- an opening is provided in the end cover which can be closed by a cover. The mother of the federal government is easily accessible through the opening.
- the single figure shows a cross section through the actuating device according to the invention for an electrically actuated valve.
- a magnet coil 2 which encloses a magnet core 3, is accommodated in an essentially pot-shaped housing 1.
- An intermediate cover 4 holds the solenoid 2 in the housing 1.
- the intermediate cover 4 holds a sealing ring 5 for sealing the solenoid 2 from other spaces of the valve.
- the housing 1 is closed by an end cover 6.
- a return plate 7 which can be actuated by the magnetic field of the magnetic coil 2 lies on one side of the magnetic coil 2 and is connected to a pin 8.
- the pin 8 is made of non-magnetizable material and has an extension in the form of an actuating pin 9.
- the actuating pin 9 extends through an opening 10 in the magnetic core 3 to the other side of the magnetic coil 2. At its one end adjacent to the yoke plate 7, the pin 8 has a collar 11. At the opposite end, the actuating pin 9 carries a valve cone 12 which, together with a valve seat 13, forms a throttle point 14. The throttle point 14 is arranged between an inlet connection 15 and a return connection 16.
- the yoke plate 7 represents the adjustable part of the actuating device, while the magnetic core 3 forms the fixed part.
- a return spring 17 in the form of a disc spring is fixed on its outer circumference in the axial direction in the housing 1. At its radially inner clamping point, the return spring 17 is held in contact with the collar 11 by a spring 18 in the form of a plate spring arranged between the return plate 7 and the return spring 17.
- a spring 18 in the form of a plate spring arranged between the return plate 7 and the return spring 17.
- the collar 11 is designed to be adjustable. This is achieved in an advantageous manner in that the collar 11 is formed by a nut which is adjustable via a thread 20 arranged on the pin 8. As described in detail above, this enables the basic air gap to be set and, in the end, the valve characteristic curve to be placed in a desired tolerance range in an auxiliary power steering system.
- the nut can also be replaced by another, equivalent fixable adjusting element, for example a pressed ring.
- an opening 21 is provided in the end cover 6, which can be closed by a cover 22, for example a screw cover.
- Opening 21 is easily accessible to the mother of the Confederation 11.
