| 发明名称 | Solenoid actuator | ||
| 摘要 | A short travel solenoid actuator (44) is disclosed which comprises at least one pole piece (47, 48), an armature (51), an electromagnet coil (46) arranged, in response to energization, to actuate the armature between first and second positions. A permanent magnet (52) is positioned and orientated so as to latch the armature in the first and second positions when the armature is in the first and second positions respectively. A spring (53) is arranged to bias the armature. | ||

| 主权项 | 1. A short travel solenoid actuator comprising: a tube or channel wherein the tube or channel is formed from a single material; at least one pole piece; an armature which lies inside the tube or channel; an electromagnet coil which lies outside the tube or channel and which is arranged, in response to energisation, to cause travel of the armature between first and second positions; a permanent magnet which lies outside the tube or channel which is positioned and orientated so as to magnetically latch the armature in the first and second positions when the armature is in the first and second positions respectively; and a spring arranged to bias the armature and configured to provide sufficient force so as to prevent the armature from latching in the second position. | ||
