Abstract
The present invention discloses an electrical actuator, comprising an electrical device and a drive train detachably associated with the electrical device for transmission of power for driving a detachably coupled external equipment.
Claims47
An electric device, comprising:
- a first mode of operation with no power supplied to the electric device;
- a first phase of a second mode of operation with power supplied to the electric device;
- and
- a second phase of the second mode of operation with power supplied to a biasing mechanism of the electric device, only.
1 more element
An electric device, comprising:
- a motor;
- a first biasing mechanism for biasing a rotor assembly of the motor to a first axial position in a first mode of operation of the electric device;
- and
- a second biasing mechanism for holding the rotor assembly of the motor in a second axial position in a second mode of operation of the electric device.
1 more element
A control circuit, comprising:
- a power source coupled with a first electromagnetic device and a second electromagnetic device;
- and
- an isolator that isolates one of a first or second electromagnetic device during one of a first or a second mode of operations of one of the first or second electromagnetic device.
A control circuit, comprising:
- a switch that is series connected with a motor, with the combine series connected motor and switch connected between a power line and neutral;
- a solenoid that is coupled in parallel with the combined series connected motor and switch, with the switch in an open condition isolating the motor from the power source while power is continuously supplied to the solenoid.
An electrical actuator, comprising:
- an electrical device;
- and
- a drive train detachably associated with the electrical device for transmission of power for driving a detachably coupled external equipment.
A valve assembly, comprising:
- a valve housing that includes a valve mechanism that controls inflow of liquid from an inlet port for a controlled outflow of liquid to an outlet port;
- the valve housing defines an axis of rotation for a valve stem that pivots about the axis of rotation for opening and closing the valve mechanism.
A mounting brace, comprising:
- an interior chamber defined by a bottom surface surrounded by a wall with top portion of the wall diverging parallel the bottom surface to form a flange;
- the bottom surface includes an opening with an alignment and engagement edge;
- the flange is for coupling the mounting brace with an actuator, and includes an alignment edge for indexing a coupling relationship with actuator;
- the bottom surface opening receiving a valve housing commensurate with alignment and engagement edge to prevent the valve housing from rotation during operation, and allow for easy installation for one of normally open or normally closed operational modes of the valve mechanism.
1 more element
A flow control system, comprising:
- a valve system;
- and
- an electrical actuator associated with the valve system by a mounting brace.
