| 20100059699 | TEMPERATURE COMPENSATED VALVE FOR GAS CHROMATOGRAPHY - Plungers and plunger assemblies for a diaphragm-sealed valve are provided. Each plunger is adpted to be received in a passage of the valve body and includes a base member and an upper member having a longitudinal play in this passage with respect to the base member. A resilient middle element is provided between the upper and base member. The base member is connected to a plunger actuating mechanism within the valve body. Optionally, the upper member may be self-aligning within the passage. The plunger can be used to compensate for temperature variations experienced by the valve in use. | 03-11-2010 |
| 20090014078 | DIAPHRAGM-SEALED VALVE HAVING INTERMEDIATE COMMUNICATION PORTS - A diaphragm-sealed valve having communication mechanisms operatively connecting neighbouring pairs of grooves is provided. Each communication mechanism has a communication port opening in an interface of a valve cap, between the neighbouring grooves. The communication mechanism also has a communication conduit extending within the valve cap and connecting the communication port and one of the neighbouring grooves. It also has a recess within a valve body aligned with the communication port and with the other one of the neighbouring grooves, a flexible sealing surface of the diaphragm being seated within the recess and resiliently biased away from the interface of the valve cap. A plunger assembly is also provided, including plungers movable to push flexible sealing surface towards the communication port. | 01-15-2009 |
