Abstract
In some examples, an apparatus can include a valve body including a valve body print substance channel and a valve body air channel, a valve socket shaped to receive the valve body, where the valve socket includes a valve socket print substance channel and a valve socket air channel, where the valve body is in a closed position such that the valve body print substance channel and the valve socket print substance channel are misaligned, and the valve body air channel and the valve socket air channel are misaligned.
Claims14
An apparatus, comprising:
- a valve body including a valve body print substance channel and a valve body air channel;
- a valve socket shaped to receive the valve body, wherein the valve socket includes a concave surface, a valve socket print substance channel, and a valve socket air channel;
- wherein when the valve body is in a closed position:
- the valve body print substance channel and the valve socket print substance channel are misaligned;
- and
- the valve body air channel and the valve socket air channel are misaligned.
A system, comprising:
- a supply reservoir including print substance;
- a valve socket, wherein the valve socket includes:
- a concave surface;
- a valve socket print substance channel;
- and
- a valve socket air channel;
- a valve body having a convex shape and located adjacent to the concave surface of the valve socket, the valve body including:
- a valve body print substance channel that is misaligned with the valve socket print substance channel in response to the valve body being in a closed position;
- and
- a valve body air channel that is misaligned with the valve socket air channel in response to the valve body being in the closed position;
- wherein the valve body is rotated from the closed position to an open position such that:
- the valve body print substance channel and the valve socket print substance channel are aligned to supply the print substance from the supply reservoir to a reservoir of an imaging device;
- and
- the valve body air channel and the valve socket air channel are aligned to vent air from the reservoir of the imaging device to the supply reservoir.
A print substance supply, comprising:
- a supply reservoir including print substance;
- a valve socket, wherein the valve socket includes:
- a concave surface;
- a valve socket print substance channel;
- and
- a valve socket air channel;
- a valve body having a convex shape and located adjacent to the concave surface of the valve socket, the valve body including:
- a valve body print substance channel that is misaligned with the valve socket print substance channel in response to the valve body being in a closed position;
- and
- a valve body air channel that is misaligned with the valve socket air channel in response to the valve body being in the closed position;
- wherein the valve body is rotated from the closed position to an open position such that:
- the valve body print substance channel and the valve socket print substance channel are aligned to supply an amount of the print substance from the supply reservoir to a reservoir of an imaging device;
- and
- the valve body air channel and the valve socket air channel are aligned to vent an amount of air from the reservoir of the imaging device to the supply reservoir, wherein the amount of air is the same as the amount of print substance.
