Electromagnetic pressure valve

摘要

The invention refers to an electromagnetic valve, in particular pressure control valve, with a magnetic part of at least an electrically controllable coil, a core and an armature provided in an armature housing and shiftably guided, and with a valve part, having at least a feed, a return and/or a consumer connection, wherein the valve part has between the feed and the return or consumer connection at least one globe valve that can be sealed by a locking part, and the armature interacts with the locking part, between armature and locking part an activation rod arranged in a penetration bore hole of the core being provided for this purpose, wherein a connecting channel, connecting the penetration bore hole with an in particular pressure-free or pressure-reduced relieving area, ends in the penetration bore hole.

主权项

1. Electromagnetic pressure valve comprising:
a magnetic part comprising:
at least one electrically controllable coil,an armature provided in an armature housing bore, anda core comprising:
a penetration bore hole andat least one connecting channel, providing fluid communication between the penetration bore hole and at least one of a pressure-free relieving area and a pressure-reduced relieving area formed between the core and a recess in the valve, to reduce transmission of fluid into the armature housing bore via the penetration bore hole; and a valve part comprising:
a feed in fluid communication with a pressurized consumer;a return connection in fluid communication with a pressurized oil circuit;at least one globe valve seat sealable by a locking part, the at least one globe valve seat disposed between the feed and the return connection; anda consumer connection in fluid communication with the pressurized consumer and disposed between the feed and the return connection, wherein the armature interacts with the locking part, via an activation rod operatively disposed through the penetration bore hole of the core and extended between the armature and the locking part.
