Abstract
A stepper motor proportionally controlled bellows valve system comprising: a valve manifold; one or more stepper motors; and one or more bellows valves. The one or more bellows valves may comprise a bellows, a sealing washer, and a profile washer. The sealing washer is configured to removeably engage with a vacuum orifice rim. The profile washers are configured to stick into the valve orifice, such that the profile washer defines a flow through the valve.
Claims20
A proportionally controlled bellows valve for regulating air flow, comprising:
- a sealing washer;
- a support washer;
- a bellows;
- a plunger adapter;
- and
- a shoulder bolt;
- wherein said plunger adapter is configured to matingly engage with a motor lead screw of a stepper motor;
- wherein said bellows is connected to said plunger adapter, such that said plunger adapter is configured to translate rotational motion of said stepper motor into linear motion of said bellows, such that said bellows is configured to compress and expand based on rotational motion of said stepper motor;
- wherein said shoulder bolt is connected to said bellows and said plunger adapter, and wherein said shoulder bolt is configured to allow said sealing washer to be mounted on said bellows;
- wherein said support washer is connected to said bellows and said sealing washer;
- and
- wherein said sealing washer is configured to releasably engage with an orifice rim of a valve manifold.
9 more elements
A stepper motor proportionally controlled bellows valve system comprising:
- one or more valve assemblies;
- wherein each of said one or more valve assemblies comprises:
- a valve manifold;
- wherein said valve manifold comprises a valve ventilation channel, an output port, a valve vacuum channel, a ventilation orifice, a ventilation orifice rim, a vacuum orifice, and a vacuum orifice rim;
- two linear stepper motors;
- wherein each of said two liner stepper motors comprises a motor lead screw;
- a motor mounting plate;
- wherein said motor mounting plate is configured to mount said two liner stepper motors to said valve manifold;
- a vacuum bellows valve;
- and
- a ventilation bellows valve;
- wherein each of said vacuum bellows valve and said ventilation bellows valve comprises:
- a support washer;
- a sealing washer;
- a bellows;
- a plunger adapter;
- and
- a shoulder bolt;
- wherein said plunger adapter is configured to matingly engage with said motor lead screw of one of said stepper motors;
- wherein said bellows is connected to said plunger adapter, such that said plunger adapter is configured to translate rotational motion of one of said stepper motors into linear motion of said bellows, such that said bellows is configured to compress and expand based on rotational motion of one of said stepper motors;
- wherein said shoulder bolt is connected to said bellows and said plunger adapter, and wherein said shoulder bolt is configured to allow said sealing washer to be mounted on said bellows;
- wherein said support washer is connected to said bellows and said sealing washer;
- wherein said sealing washer is configured to releasably engage with one of said ventilation orifice rim and said vacuum orifice rim;
- wherein said shoulder bolt is configured to allow mounting of a profile washer, such that said profile washer is configured to protrude into one of said ventilation orifice and said vacuum orifice of said valve manifold, such that a shape and position of said profile washer defines a flow of fluid through one of said ventilation orifice and said vacuum orifice.
