Modular jetting devices

Modular devices for jetting a fluid material and components for modular jetting devices. The devices may include a pressurized air or positive displacement pump (102) fluid supply module to supply a fluid module inlet (42). A syringe (22) may feed material through a check valve (104) to a positive d...

Zusammenfassung:	Modular devices for jetting a fluid material and components for modular jetting devices. The devices may include a pressurized air or positive displacement pump (102) fluid supply module to supply a fluid module inlet (42). A syringe (22) may feed material through a check valve (104) to a positive displacement pump (102), which feeds material through another check valve to the fluid module. Inside the fluid module is a valve element (14) moved to contact a valve seat and jet a droplet of material by contact between an external drive pin and a movable element of the fluid module. Either a piezoelectric actuator, a pneumatic actuator, or another actuator may move the drive pin. A controller may coordinate the supply of fluid from the positive displacement pump with the rate at which material is jetted. The fluid module and positive displacement pump are easily removable from the jetting device.
