Biased actuator systems
An actuator system including a receiving body defining a mounting bore, a inlet fluid channel, an outlet fluid channel and a connecting channel between the inlet fluid channel and the outlet fluid channel, a valve seat disposed within the connecting channel, and an actuator assembly connected to the receiving body, the actuator assembly including a sealing tip extending into the mounting bore, the sealing tip being adapted to sealingly engage the valve seat.
1 . An actuator system comprising:
a receiving body defining a mounting bore, an inlet fluid channel, an outlet fluid channel and a connecting channel between said inlet fluid channel and said outlet fluid channel;
a valve seat disposed within said connecting channel; and
an actuator assembly connected to said receiving body, said actuator assembly including a sealing tip extending into said mounting bore, said sealing tip being adapted to sealingly engage said valve seat.
2 . The system of claim 1 wherein said receiving body is a hydraulic modulator.
3 . The system of claim 1 wherein said valve seat is press fit into said connecting channel.
4 . The system of claim 1 wherein said valve seat is formed from a hardened material.
5 . The system of claim 1 wherein said sealing tip disengages said valve seat when an effective magnetic field is applied to said actuator assembly.
6 . The system of claim 1 wherein said sealing tip sealingly engages said valve seat when an effective magnetic field is applied to said actuator assembly.
7 . The system of claim 1 further comprising a biasing device positioned in said mounting bore, said biasing device being adapted to bias said sealing tip away from said valve seat.
8 . The system of claim 1 wherein said actuator assembly further includes a plunger, a housing and a rod, and wherein said sealing tip is positioned on said rod.
9 . The system of claim 1 wherein said actuator assembly further includes a plunger, a stop and a biasing device adapted to bias said plunger away from said stop.
10 . The system of claim 9 wherein said sealing tip is positioned on said plunger.
11 . A normally closed actuator system comprising:
a receiving body defining a mounting bore, an inlet fluid channel, an outlet fluid channel and a connecting channel between said inlet fluid channel and said outlet fluid channel;
a valve seat disposed within said connecting channel; and
an actuator assembly including a cup having a closed proximal end and an open distal end, said open distal end being connected to said receiving body, a stop fixedly disposed within said cup, a plunger slideably received within said cup, said plunger including a distal end extending into said mounting bore, said distal end including a sealing tip, and a biasing device disposed between said stop and said plunger to urge said plunger away from said stop such that said sealing tip engages said valve seat.
12 . The system of claim 11 wherein said receiving body is a hydraulic modulator.
13 . The system of claim 11 wherein said valve seat is press fit into said connecting channel.
14 . The system of claim 11 wherein said valve seat is formed from a hardened material.
15 . The system of claim 11 wherein said sealing tip disengages said valve seat when an effective magnetic field is applied to said actuator assembly.
16 . A normally open actuator system comprising:
a receiving body defining a mounting bore, an inlet fluid channel, an outlet fluid channel and a connecting channel between said inlet fluid channel and said outlet fluid channel;
a valve seat disposed within said connecting channel;
an actuator assembly including a cup having a proximal end and a distal end, a housing defining an elongated channel, said housing including a distal end connected to said receiving body and a proximal end connected to said distal end of said cup, and a rod slideably received within said elongated channel, said rod including a distal end extending into said mounting bore, said distal end including a sealing tip; and
a biasing device positioned in said mounting bore to bias said distal end of said rod away from said valve seat.
17 . The system of claim 16 wherein said receiving body is a hydraulic modulator.
18 . The system of claim 16 wherein said valve seat is press fit into said connecting channel.
19 . The system of claim 16 wherein said valve seat is formed from a hardened material.
20 . The system of claim 16 wherein said sealing tip sealingly engages said valve seat when an effective magnetic field is applied to said actuator assembly.
