Pressure buffer, liquid injection head, liquid injection recorder and pressure buff method

摘要

Precision detecting pressure well with the type of liquid, the pressure buffer which it can control, offer the liquid injection head, and the liquid injection recorder. In order the substance section to seal up 91 where the pipe conduit 93 which opens to the concave section 91a because the liquid is made to store and concave section 91a and 94 was formed and concave section 91a, the thin film 96 which is arranged and is locked to substance section 91 in margin 91c of concave section 91a and thin film 96 and being connection separation unrestricted, the displacement quantitative detection expedient which possesses the loop coil section 99 which detects the displacement of relative position of the standard component 97 which accompanies the pressure fluctuation of the liquid which is stored in the standard component 97 which is arranged inside concave section 91a and concave section 91a with non contact vis-a-vis standard component 97It has.
