Abstract
Example implementations relate to printer valve seals. In some examples, a printer valve to receive print substance from a fluid conduit and transmit the received print substance to a print cartridge can include a valve neck having a first seal member to provide a seal between the valve neck and an inlet of the print cartridge, and an actuator having a second seal member to form a seal within a valve body of the printer valve while the valve neck is detached from the inlet of the print cartridge.
Claims8
A system, comprising:
- a print cartridge comprising an inlet having an internal dimension;
- a printer valve to receive print substance from a fluid conduit and transmit the received print substance to the inlet, the printer valve comprising:
- a valve neck having a first seal member having an external dimension that exceeds the internal dimensions of the inlet to provide a seal between the valve neck and the inlet responsive to insertion of the valve neck into the inlet;
- a valve body having a biasing member;
- and
- an actuator located in the valve neck and the valve body and having a second seal member, wherein:
- the biasing member is in an extended state while the valve neck is detached from the inlet of the print cartridge to form a seal within the valve body of the printer valve via the second seal member and maintain a negative pressure within the valve body;
- the actuator is to contact the inlet to cause an application of force to the actuator after the first seal member is to provide the seal between the valve neck and the inlet;
- and
- the biasing member is to move from the extended state to a compressed state to enable flow of the print substance from the printer valve to the print cartridge.
