Abstract
A valve assembly consists essentially of a valve body having an inlet port and an outlet port; a valve retainer at least partially housed within the valve body; a valve poppet positioned within the valve body; a magnet affixed within the valve body near the valve body inlet port; and a solenoid coil mounted around the valve body.
Claims17
A valve assembly, consisting essentially of:
- a valve body having an inlet port and an outlet port;
- a valve retainer extending from the valve body and configured to threadably engage with a pipe section;
- a valve poppet positioned within the valve body;
- a magnet positioned within the valve body between the poppet and the valve retainer;
- and
- a solenoid coil mounted to the valve body;
- wherein the valve body and the valve retainer are each constructed of a non-magnetic material;
- and
- wherein the valve poppet is constructed of a magnetic material.

A valve assembly, comprising:
- a valve body having an inlet port and an outlet port;
- a valve retainer threadably coupled to and extending from the valve body and configured to threadably engage with a pipe section;
- a valve poppet positioned within the valve body;
- a magnet arranged within the valve body;
- a magnet retainer arranged within the valve body, wherein the magnet retainer holds the magnet;
- and
- a solenoid coil mounted to the valve body.
4 more elements
A method for operating a valve assembly, comprising:
- providing a valve assembly, the valve assembly consisting essentially of:
- a valve body having an inlet port and an outlet port and comprising a ledge and a valve seat;
- a magnet retainer within the valve body, the magnet retainer housing a magnet;
- a valve retainer at least partially housed within the valve body, wherein the valve retainer maintains the magnet retainer in position within the valve body;
- a seal positioned between the magnet retainer and the valve retainer;
- a valve poppet positioned within the valve body between the valve body outlet port and the magnet retainer;
- at least one pin extending through the magnet retainer to guide movement of the valve poppet;
- a solenoid coil mounted around the valve body, the solenoid coil being battery operated;
- and
- a micro charger for maintaining the life of the battery;
- causing a pulse of electrical current of a first polarity to be sent to the solenoid coil, thereby inducing a first magnetic field, wherein:
- the first magnetic field causes the valve poppet to be temporarily magnetized such that the valve poppet is attracted to the magnet within the magnet retainer;
- and
- the magnet holds the valve poppet at the magnet retainer such that the valve assembly is in an open configuration;
- causing a pulse of electrical current of a second polarity to be sent to the solenoid coil, thereby inducing a second magnetic field, wherein:
- the second magnetic field causes the valve poppet to be temporarily magnetized such that the valve poppet is repelled by the magnet within the magnet retainer;
- and
- the valve poppet sits atop the valve seat such that the valve assembly is in a closed configuration;
- wherein, in the open configuration, fluid is permitted to flow through the valve assembly, and in the closed configuration, fluid is prevented from flowing through the valve assembly.
