Abstract
A fluid transfer assembly comprises two parallel fluid transfer paths and a shared, linear path actuator for providing positive sequencing of input and output valves of both paths. Corresponding valves of the two paths share a lever assembly which is rotated between first and second positions by reciprocal movement of the liner path actuator.
Claims10
A fluid transfer assembly comprising:
- at least one transfer path assembly (110) comprising:
- an input port (115), an input valve (151), a transfer chamber (155), a transfer input-output port (114), an output valve (152), and an output port (116);
- and
- control means (140) for adjusting said input and output valves characterized in that
- said control means (140) comprises first and second lever assemblies (162, 163), coupled respectively to said input and output valves (151, 152), for respectively adjusting said input and output valves (151, 152), mechanical actuator means (143, 144) for positioning said lever assemblies (162, 163) in fixed transfer sequences such that said input and output ports (115, 116) are precluded from being in simultaneous communication with said transfer chamber (155), and means (141, 142) for controlling said mechanical actuator means.
