This disclosure concerns a method for removing gas and/or gas bubbles from a liquid medicament stored in a reservoir for an infusion pump device. The reservoir comprises a displacing member which is at least partly displaceable relative to the reservoir thereby enabling receiving mechanical oscillations in order to generate mechanical waves in the liquid medicament. The method comprises: providing the reservoir; and transmitting a mechanical oscillation to the displacing member of the reservoir thereby generating a mechanical wave in the liquid medicament for removing gas and/or gas bubbles from the liquid medicament.

The air eliminator valve helps to eliminate air in the plastic resin used for composite products manufacturing. During operation, it continuously eliminates the air bubbles in the plastic resin running through the valve, and then transfers the filtered plastic resin into the mold. The design of the air eliminator valve consists of: inlet, inlet lock, air vent, upper cover, main body, ultrasonic generator, outlet lock and outlet. In which, the ultrasonic generator plays a role in generating ultrasonic waves to the plastic resin in the valve body that allows speeding up the air releasing process out the plastic resin. The air content in the valve could go out through the air vent on the upper cover, its status open/close is controlled by airlock with automatic response mechanism.

A device for degassing and/or dehydrating a hydraulic oil includes a flow lance, a flow duct, and a decoupling module. The flow lance includes a restriction site via which the hydraulic oil flows under a high pressure drop. The flow duct is configured as a pipe that is located downstream of the restriction site. The quantity of oil that flows via the restriction site and a throughflow cross section of the restriction site are coordinated to one another such that a cavitation zone or supercavitation zone forms downstream of the restriction site. The flow duct has a significantly larger cross section with respect to the throughflow cross section of the restriction site. For a quiet operation of the device, the flow lance is held in the decoupling module via which the flow lance is configured to be fastened in a vibration-decoupled manner to a tank.

The present invention discloses a method for improving the solenoid dispensing water resistance, comprising a base, said base top surface of the fixed mounting support column slidably mounted threaded rod of the boom, the bottom of the threaded rod fixedly mounted may coil for dispensing of the dispensing head, when the dispensing start lifting the motor, the lifting motor drives a first gear, a first gear rotatably drives the second gear, the second gear rotates the threaded rod may be down to the coil dispensing improved dispensing manner, increasing the efficiency of dispensing can be generated after a significant reduction dispensing bubbles, to improve the quality of the coil, glue extrusion by pressurizing the way, bubbles in the glue are deposited After the dispensing is completed, use the vibration method to shake the air bubbles in the coil to make the coil have better quality.
