Abstract

A valve assembly embodiment includes first and second valve devices and a coupling mechanism. Each of the first and second valve devices can include first and second fluid pathways and first and second valve members respectively positioned at the first and second fluid pathways. Both the first and second valve members can have an open position that permits fluid flow and a closed position that prevents fluid flow along the first and second fluid pathways past the first and second valve members. The coupling mechanism can couple to each of the first and second valve members. When the valve assembly is actuated, the coupling mechanism can be configured to transition one or both of the first and second valve members between the open and closed positions.

Dependent claims

A valve assembly comprising:

a first valve device comprising a first fluid pathway and a first valve member, the first valve member positioned at the first fluid pathway, the first valve member having a first valve member open position that permits fluid flow along the first fluid pathway past the first valve member and a first valve member closed position that prevents fluid flow along the first fluid pathway past the first valve member;
a second valve device comprising a second fluid pathway and a second valve member, the second valve member positioned at the second fluid pathway, the second valve member having a second valve member open position that permits fluid flow along the second fluid pathway past the second valve member and a second valve member closed position that prevents fluid flow along the second fluid pathway past the second valve member;
and
a coupling mechanism coupled to each of the first valve member and the second valve member, wherein when the valve assembly is actuated the coupling mechanism is configured to move each of the first valve member from the first valve member open position to the first valve member closed position and the second valve member from the second valve member closed position to the second valve member open position,
wherein the coupling mechanism includes a plurality of actuation sections spaced about a periphery of the coupling mechanism,
wherein the plurality of actuation sections together span a perimeter surface of the coupling mechanism,
wherein each of the plurality of actuation sections has an aperture,
wherein one or both of the first valve fluid pathway and the second valve fluid pathway extend between more than two apertures,
wherein at least one of the first valve fluid pathway and the second valve fluid pathway serves as a fluid inlet, and
wherein at least one of the first valve fluid pathway and the second valve fluid pathway serves as a fluid outlet.

A fluid injection system comprising:

a reservoir defining an interior reservoir volume, the reservoir including a plunger positioned within the interior reservoir volume;
a drive assembly configured to move the plunger within the interior reservoir volume to draw an injection fluid into the reservoir and to expel the injection fluid from the reservoir;
and
a valve assembly fluidly connected to the reservoir, the valve assembly comprising:
a first valve device comprising a first fluid pathway and a first valve member, the first valve member positioned at the first fluid pathway, the first valve member having a first valve member open position that permits fluid flow along the first fluid pathway past the first valve member and a first valve member closed position that prevents fluid flow along the first fluid pathway past the first valve member;
a second valve device comprising a second fluid pathway and a second valve member, the second valve member positioned at the second fluid pathway, the second valve member having a second valve member open position that permits fluid flow along the second fluid pathway past the second valve member and a second valve member closed position that prevents fluid flow along the second fluid pathway past the second valve member;
and
a coupling mechanism coupled to each of the first valve member and the second valve member, wherein when the valve assembly is actuated the coupling mechanism is configured to move each of the first valve member from the first valve member open position to the first valve member closed position and the second valve member from the second valve member closed position to the second valve member open position,
wherein the coupling mechanism includes a plurality of actuation sections spaced about a periphery of the coupling mechanism,
wherein the plurality of actuation sections together span a perimeter surface of the coupling mechanism,
wherein each of the plurality of actuation sections has an aperture,
wherein one or both of the first valve fluid pathway and the second valve fluid pathway extend between more than two apertures,
wherein at least one of the first valve fluid pathway and the second valve fluid pathway serves as a fluid inlet, and
wherein at least one of the first valve fluid pathway and the second valve fluid pathway serves as a fluid outlet.
