Definitions
- the invention relates to a submersible anchor system for an electropneumatic pressure transducer, comprising at least partially in a casing, in particular an iron casing, a Submersible anchor, a core, such as an iron core or a magnetic core, at least one first recess in the plunger anchor and / or a second recess in the core and an air gap between the casing and the plunger and / or the core, the by relative movement between the plunger and the core during which the Submersible anchor in the second recess in the core and / or the core in the first recess is at least partially movable in and out of the plunger, is adjustable.
- a submersible anchor system for an electropneumatic pressure transducer comprising at least partially in a casing, in particular an iron casing, a Submersible anchor, a core, such as an iron core or a magnetic core, at least one first recess in the plunger anchor and / or a second recess in the core and an air gap between the
- Such an immersion anchor system is known, for example, from DE 41 10 003 C1.
- there includes the well-known electropneumatic converter which is used in particular in a pneumatic Control of a motor vehicle can be used, a valve device by a membrane and the plunger system is actuated and in a valve chamber a mixed pressure from air at low pressure and atmospheric pressure by controlling the corresponding Connections generated, which is supplied to a consumer via a connection.
- the Submersible anchor system is characterized by the possibility of adjusting the air gap between the iron sheathing and the submersible anchor, i.e. in the magnetic circuit. Furthermore fulfilled the air in the air gap damping properties, but only as long as the air gap more or less sealed, so there is no leakage.
- the object of the present invention is therefore the generic submersible anchor system to develop in such a way that the disadvantages of the prior art are overcome, in particular, a metallic stop of the submersible anchor and core is avoided Prevention of mechanical damage to the submersible anchor and / or core and for Reduction of noise emissions, especially under vibration or at Jump function, in a large area of application.
- This object is achieved according to the invention by a first attenuator in the first Recess and / or a second attenuator in the second recess.
- first and / or second damping member is formed from an elastomer is or are.
- Advantageous embodiments of the invention can be characterized in that the Core is formed in two parts, the second recess is formed in the first core part, and the second core part extends through the second recess and into the first recess is movable in or out of the same.
- the first core part is essentially concentric in a ring shape is around the second core portion and the second attenuator is substantially annular.
- the invention proposes that the second core part be substantially cylindrical and the first attenuator is substantially plug-like.
- the core in particular the first core part, is movable via a threaded sleeve relative to the plunger to adjust the air gap.
- the second core part in the first core part is arranged adjustable, the second core part preferably at its the End facing away from the plunger anchor can be attacked for adjusting the air gap.
- first and / or second core part have a Has or have tapered cone section in the direction of the plunger.
- a plain bearing bush for the plunger anchor can be provided according to the invention.
- the invention is therefore based on the surprising finding that inexpensive How the wear of a submersible anchor system is reduced and its area of use can be enlarged by the air gap of the magnetic circuit in an electropneumatic Pressure converter essentially only the function of setting the electro-pneumatic Pressure transducer is used while damping properties of at least one additional attenuator are taken over between the plunger and the Core is provided, namely in a recess in the core and / or in a recess in the diving anchor.
- the attenuator reliably prevents a metallic one Stop of the submersible anchor and core without the need for a complex air gap seal got to; the attenuator also attenuates sound to reduce noise emissions the electropneumatic pressure transducer; and the attenuator is preferably made of one Formed elastomer, which has a low temperature dependence and thus the Application area of the electropneumatic pressure transducer enlarged.
- an immersion anchor system 1 comprises within a coil 2 has a plunger anchor 10 with a first recess 12 in its one Not shown membrane of the electropneumatic pressure transducer end facing away.
- the first recess 12 is essentially cylindrical with a conically tapering The End.
- the submersible anchor 10 runs at least partially in an iron casing 14, which also surrounds the coil 2 and at least part of an iron core.
- the iron core in turn comprises two components, a first iron core part 16 with one second recess 18 is formed, in which the second iron core part 20 extends.
- the Submersible anchor 10 is also guided in a slide bearing bush 22 in the iron casing 14, while the first iron core part 16 is mounted in a threaded sleeve 24, which in turn by an abutment against the iron casing 14 is prevented by a spacer 26.
- the first recess 12 in the plunger anchor 10 is a damping plug 28, in particular in the form of an elastomer partially filling the first recess 12, and in The second recess 18 in the first iron core 16 is a damping ring 30, in particular in the form of an elastomer partially filling the second recess 18.
- An air gap 32 is finally between the plunger 10, the spacer 26 and the iron core 16, 18 formed.
- the size of the air gap 32 is for adjustment the electropneumatic pressure transducer by moving the first iron core part 16, namely by rotating the threaded sleeve 24 and / or moving the second iron core part 20, namely by rotating the same in the second iron core part 20, relative to Submersible anchor 10 possible.
- Diving anchor system 1 prevent the damping ring 28 and the damping plug 30 from metallic stop of the first iron core 16 or the second iron core 20 on the Submersible anchor 10, which is the average lifetime of the submersible anchor system 1 due to the reduction in damage and secondly the noise emission reduced, advantageously over a wide temperature range due to the low temperature dependence of the for the damping ring 28 and the damping plug 30 elastomer used.
