VALVE APPARATUS AND WASHER APPARATUS

摘要

An object of the present invention is to provide a valve apparatus capable of keeping a holding state of a valve body. The valve apparatus 14 is adapted to supply cleaning fluid by switching between a first flow channel 54 and a second flow channel 55, the valve apparatus 14 being provided with: a first fluid pipe 44 having a first flow channel 54; a second fluid pipe 45 coaxially aligned with the first fluid pipe 44, the second fluid pipe 45 having a second flow channel 55; a housing 86 provided with a first valve chamber 37 and a second valve chamber 38; a partition wall 49 disposed between the first flow channel 44 and the second flow channel 55 in the housing 86; and a rib 46 provided to the housing 86 to support the partition wall 49, wherein the partition wall 49 has: a film-like valve body 50 which is elastically deformed by pressure of the first valve chamber 37 and the second valve chamber 38 so as to open one of the first flow channel 44 and the second flow channel 55 and close the other of the first flow channel 54 and the second flow channel 55; and a frame 51 attached along an outer circumference of the valve body 50 and supported by the rib 56, wherein the frame 51 is higher in stiffness than the valve body 50.
