Abstract: This disclosure includes electrohydrodynamic (EHD) printer nozzles, associated printer heads and printers, and methods for using the same. Some EHD nozzles include a circuit with at least one depressible electrical connector and a housing configured to receive a dispensing device such that electrical communication is permitted between the at least one depressible electrical connector and a conductive tip of the dispensing device, where the housing is further configured to be releasably coupled to a printer head such that voltage can be applied across the conductive tip. Some nozzles include an additional electrode. Some of the present methods include inserting a dispensing device into an EHD nozzle having a housing with a depressible electrical connector such that the connector contacts a conductive tip of the dispensing device and applying a voltage across the conductive tip. Others of the present methods include performing maskless lithography with the present EHD printers and components.

Abstract: The present invention relates to a compressor, which has ribs for directly supporting a part of a valve plate in a suction chamber of a housing, thereby preventing a noise caused by vibration of the valve plate during the strike of a suction reed valve.
