MICROJET CARTRIDGE WITH PARALLEL PNEUMATIC INTERFACE CARD Russian patent published in 2015 - IPC B01L3/00 

FIELD: measurement equipment.

SUBSTANCE: cartridge contains three-dimensional channel (103) for fluid medium, in which fluid medium (104) should move, and flexible diaphragm (105). Flexible diaphragm stretches in the plane and is a part of cartridge external surface, and boundaries in space of three-dimensional channel for fluid medium are determined in three coordinates by internal walls of cartridge and the flexible diaphragm. The flexible diaphragm is in ground state without impact of pressure and vacuum on it and is designed with possibility to incurve relative to the ground state under impact of pneumatic forces perpendicular (106) to the plane of flexible diaphragm in two directions, when cartridge is located on parallel pneumatic interface card. Pneumatic interface card (101) is located between this cartridge and pneumatic measuring device (102) and contains a side directed to measuring device (119), when interface card is installed in measuring device, and to the side directed to cartridge, when cartridge is located on interface card. Also the card contains pneumatic channel (122, 123, 138) for connection of pneumatic fluid medium of pneumatic measuring device with the side directed to the measuring device to the side directed to the cartridge in order to provide pneumatic actuation of flexible diaphragm of microjet cartridge.

EFFECT: providing improved simplified and low-cost procedure of actuation of fluid medium in microjet systems.
