Abstract
Improving milking system performance through the incorporation of a source of greater than atmospheric pressure air into a pulsator while limiting total pressure in the teat cup. The system is further improved by providing an improved supply of regulated vacuum to the milking cluster throughout the milking process. The system is further improved with a monitoring and detecting the functional failure of the pulsation assemblies. Additional system improvements are provided with the addition of a fresh air valve assembly, a wireless method of regulating vacuum levels and the remote location of a pulsator assembly in a basement style parlor.
Claims9
A pulsator for alternatingly supplying air and vacuum to a pulsation chamber to open and close a flexible liner of a teat cup assembly of a milking system attached to an animal comprising:
- a first valve comprising:
- a first solenoid housing having a first end open to a channel and a second end;
- a first solenoid having an interior end, located within the channel of the first solenoid housing;
- a respective inlet and a respective outlet through which greater than atmospheric pressure air can be respectively supplied to the pulsation chamber of the teat cup assembly;
- and
- a first solenoid valve plunger reciprocally movable in the first solenoid housing with a first end in the channel for sealing the inlet from the outlet and a second end opposite the first end;
- a second valve comprising:
- a second solenoid housing having a first end open to a channel and a second end
- a second solenoid having an interior end, within the channel of the second solenoid housing;
- a respective inlet and a respective outlet through which a vacuum can be respectively supplied to the pulsation chamber of the teat cup assembly;
- and
- a second solenoid valve plunger reciprocally movable in the second solenoid housing with a first end in the channel for sealing the inlet from the outlet and a second end opposite the first end;
- a common outlet operatively connected to both the valves through which air pressure and vacuum are alternately supplied to the pulsation chamber of the teat cup assembly from the first and second valves, respectively;
- and
- a controller connected to the first solenoid of the first valve and the second solenoid of the second valve, the controller respectively actuating and deactivating the first and second valves to provide alternating supply of greater than atmospheric pressure air and vacuum to the common outlet, with the first and second valve never being simultaneously actuated.
