Abstract

An example of a device (100) may include a valve body (108). The device (100) may include a printing substance transfer aperture (122) through the valve body (108). The device (100) may include a hood (138), fixed to the valve body (108), encompassing the printing substance transfer aperture (122) within a cavity between an external face (137) of the valve body (108) and the hood (138). The device (100) may include a printing substance dispensing nozzle (110) movable between a first position with an orifice (126) of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second position with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer aperture (122). The device (100) may include a dispensing-side gasket material (132) slide-able through the printing substance transfer aperture (122) when moving the printing substance dispensing nozzle (110) between the first position and the second position.

First claim

What is claimed:

1. A device, comprising:
a valve body;
a printing substance transfer aperture through the valve body;
a hood, fixed to the valve body, encompassing the printing substance transfer aperture within a cavity between an external face of the valve body and the hood;
a printing substance dispensing nozzle movable between a first position with an orifice of the printing substance dispensing nozzle facing an internal face of the valve body and a second position with the orifice of the printing substance dispensing nozzle facing the printing substance transfer aperture; and
a dispensing-side gasket material slide-able through the printing substance transfer aperture when moving the printing substance dispensing nozzle between the first position and the second position.

2. The device of claim 1 , wherein the hood includes a first wall opposing the external face of the valve body and a plurality of sidewalls connecting the first wall to the valve body.

3. The device of claim 2 , wherein the external face of the valve body, the first wall of the hood opposing the external face of the valve body, and the plurality of sidewalls of the hood encompass an opening into the cavity.

4. The device of claim 1 , wherein walls of the hood define a geometry of the cavity matched to a geometry of a receiving-side mating interface to accommodate an insertion of the receiving-side mating interface within the cavity.

5. The device of claim 1 , wherein the device includes a lock mechanism to lock the printing substance dispensing nozzle in the first position.

6. The device of claim 5 , wherein the lock mechanism is actuatable to unlock the printing substance dispensing nozzle from the first position responsive to insertion of a receiving-side mating interface, with a complementary geometry to a geometry of the cavity, within the cavity.

7. A device, comprising:
a valve body including a curved internal face spanning between a pair of flat internal faces;
a printing substance transfer aperture through the curved internal face of the valve body;
a shielding body to shield the printing substance transfer aperture and define a geometry of a receiving-side mating interface permitted to interface with the printing substance transfer aperture;
a printing substance dispensing nozzle, including a curved external face spanning between a pair of flat external faces, movable between a first position with an opening of the printing substance dispensing nozzle facing the curved internal face and a second position with the opening of the printing substance dispensing nozzle facing the printing substance transfer aperture; and
a dispensing-side gasket material slide-able against the curved internal face of the valve body and through the printing substance transfer aperture when moving the printing substance dispensing nozzle between the first position and the second position.

8. The device of claim 7 , further comprising a locking rod channel in the pair of flat external faces of the printing substance dispensing nozzle to engage a locking rod in a first portion of the locking in channel to lock the printing substance dispensing nozzle in the first position.

9. The device of claim 8 , including a locking rod aperture through each face of the pair of flat external faces, wherein the locking rod aperture is dimensioned to accommodate a movement of the locking rod between a first locked position and a second unlocked position within the locking rod aperture.

10. The device of claim 9 , wherein the movement of the locking rod to the second unlocked position within the locking rod aperture introduces the locking rod in to a second portion of the locking rod channel in the pair of flat external faces of the printing substance dispensing nozzle and frees the printing substance dispensing nozzle to rotate to the second position.

11. The device of claim 9 , wherein the locking rod is movable in to the second unlocked position within the locking rod aperture responsive to the geometry of the receiving-side mating interface interlocking with the geometry of the shielding body.

12. A system, comprising:
a dispensing-side mating interface, including:
a valve body;
a printing substance transfer aperture through the valve body; a hood, fixed to the valve body, encompassing the printing substance transfer aperture within a cavity between an external face of the valve body and the hood;
a printing substance dispensing nozzle movable between a first position with an orifice of the printing substance dispensing nozzle facing an internal face of the valve body and a second position with the orifice of the printing substance dispensing nozzle facing out of the printing substance transfer aperture;
a dispensing-side gasket material slide-able through the printing substance transfer aperture when moving the printing substance dispensing nozzle between the first position and the second position; and

a receiving-side mating interface, having a complementary geometry to a geometry of the cavity, to slide within the cavity and engage with a geometry of the hood to receive the printing substance through the printing substance transfer aperture.

13. The system of claim 12 , wherein a geometry of the hood is to block insertion of an object, without the complementary geometry to the geometry of the cavity, within the cavity and prevent the object from actuating a locking mechanism of the dispensing-side mating interface to unlock the printing substance dispensing nozzle from the first position.

14. The system of claim 12 , wherein the printing substance dispensing nozzle is locked in the first position until the receiving-side mating interface is fully inserted within the cavity.

15. The system of claim 12 , wherein the receiving-side mating interface includes a printing substance inlet port and the printing substance dispensing nozzle is locked in the first position until the printing substance inlet port is aligned with the printing substance transfer aperture within the cavity.
