Abstract
A pulsator comprises a valve chamber and an armature arranged in the valve chamber. An electrically powered coil at least partially surrounds the valve chamber and generates a magnetic flux. A magnetic pole piece is arranged in the valve chamber and has a metal surface. The armature has a first end nearest the magnetic pole piece and a second end. The first end of the armature has a metal surface and the second end has a first sealing surface and a second sealing surface.

A pulsator, comprising:
- a valve chamber;
- an electrically powered coil at least partially surrounding the valve chamber and operable to generate a magnetic flux;
- a magnetic pole piece arranged in the valve chamber and having a metal surface;
- and
- an armature arranged in the valve chamber and having a first end nearest the magnetic pole piece and a second end, wherein the first end of the armature has a metal surface and the second end has a first sealing surface and a second sealing surface.
A three-port valve used to apply alternately atmospheric pressure from a first port and vacuum pressure from a second port to a third port, the valve comprising a magnetic pole piece and an armature with a first end near the pole piece and first and second sealing surfaces located near a second, opposite, end of the armature, wherein an electrically powered coil generates a magnetic flux that causes a magnetic attraction between the pole piece and the armature.
A pulsator, comprising:
- a valve chamber;
- an electrically powered coil at least partially surrounding the valve chamber and operable to generate a magnetic flux;
- a magnetic pole piece arranged in the valve chamber and having a metal surface;
- and
- an armature arranged in the valve chamber and having a first end nearest the magnetic pole piece and a second end, wherein the first end of the armature has a metal surface and the second end has a first sealing surface and a second sealing surface;
- wherein:
- in a first mode of operation, the coil activates to generate a magnetic flux which causes the armature to move into a first position in the valve chamber in response to a magnetic attraction between the metal surface of the pole piece and the metal surface of the armature, wherein the first sealing surface of the armature creates a seal;
- and
- in a second mode of operation, the coil deactivates such that the armature moves into a second position in the valve chamber, wherein the second sealing surface of the armature creates a seal.
