Z-shaped fluid channel arrangement
The invention is related to a manifold comprising at least two valve receptacles, further comprising a fluid groove arrangement comprising at least two fluid grooves, wherein a first fluid groove of the at least two fluid grooves has a starting point near a first valve receptacle of the at least two valve receptacles and an end point near a second valve receptacle of the at least two valve receptacles and wherein a second fluid groove of the at least two fluid grooves has a starting point near a second valve receptacle of the at least two valve receptacles. The invention is further related to an apparatus comprising a manifold of the aforementioned kind and further comprising an inner body of a dispense interface.
1. A manifold comprising:
a first valve receptacle;
a second valve receptacle;
a first fluid groove having a starting point near or at the first valve receptacle and an end point near or at the second valve receptacle;
a second fluid groove having a starting point near or at the second valve receptacle,
a filling block, wherein the filling block is a rectangular protrusion; and
a fluid connection between the second fluid groove and the filling block
wherein the second valve receptacle provides fluid communication between the first fluid groove and the second fluid groove; and
wherein the filling block, the first fluid groove, and the second fluid groove are arranged on a surface of the manifold.
2. The manifold according to claim 1 , wherein the first valve receptacle is a first valve cavity and the second valve receptacle is a second valve cavity.
3. The manifold according to claim 1 , wherein each of the first valve receptacle and the second valve receptacle is positioned in a respective convex protrusion on a surface of the manifold.
4. The manifold according to claim 3 , wherein each of the first valve receptacle and the second valve receptacle is positioned in the center of the respective convex protrusion.
5. The manifold according to claim 1 , wherein the outward appearance of the manifold is Y-shaped.
6. An apparatus comprising:
a manifold comprising:
a first valve receptacle;
a second valve receptacle; and
a fluid groove arrangement comprising a first fluid groove and a second fluid groove;
wherein the first fluid groove has a starting point near or at the first valve receptacle and an end point near or at the second valve receptacle,
wherein the second fluid groove has a starting point near or at the second valve receptacle, and
wherein the second valve receptacle provides fluid communication between the first fluid groove and the second fluid groove;
an inner body of a dispense interface, wherein the inner body comprises a holding chamber configured for housing a filling block and further configured for fluid outflow from the inner body;
a first valve structure at least partially received by the first valve receptacle;
a second valve structure at least partially received by the second valve receptacle;
a first reservoir defined by the inner body;
a second reservoir defined by the inner body;
wherein the first valve structure is configured, in a first state, to provide a fluid seal between the first reservoir and the fluid groove arrangement and configured, in a second state, to enable fluid flow from the first reservoir to the fluid groove arrangement,
wherein the second valve structure is configured, in a first state, to provide a fluid seal between the second reservoir and the fluid groove arrangement and configured, in a second state, to enable fluid flow from the second reservoir to the fluid groove arrangement, and
wherein the inner body is arranged with the manifold such that any fluid flowing from the first reservoir to the holding chamber via the first valve structure or any fluid flowing from the second reservoir to the holding chamber via the second valve structure flows first through the second fluid groove.
7. The apparatus according to claim 6 , wherein the first valve structure is configured to block fluid flow from the first reservoir to the starting point of the first fluid groove in a first state and to enable fluid flow from the first reservoir to the starting point of the first fluid groove in a second state.
8. The apparatus according to claim 6 , wherein the second valve structure is configured to block fluid flow from the second reservoir to the starting point of the second fluid groove in a first state and to enable fluid flow from the second reservoir to the starting point of the second fluid groove in a second state.
9. The apparatus according to claim 6 , wherein the first valve structure comprises a diaphragm valve the diaphragm valve comprising a circular protrusion configured to be seated in the first valve receptacle, wherein the diaphragm valve is substantially cup-shaped, and wherein in a first state the diaphragm valve is facing the first valve receptacle with the diaphragm valve's convex side and is un-stressed.
10. The apparatus according to claim 9 , wherein the diaphragm valve is configured to invert its cup-shape under fluidic pressure and wherein the cup-shape of the diaphragm valve is inverted in a second state.
