An electromagnetic reed valve comprises a pressing member which is mounted at a plunger. The pressing member is urged by a spring toward a reed valve body, so that the pressing member urges at least that portion of the reed valve body which confronts the outlet of a valve chamber, when the outlet is closed by the reed valve body.
