To provide a liquid supply control valve including a pressure absorption mechanism absorbing pressure fluctuation of a secondary side flow passage and having excellent durability.
A liquid supply control valve has a flow passage block 10 where a primary side flow passage 11 and a secondary side flow passage 12 are formed, and a communication chamber 17 communicating the primary side flow passage 11 and the secondary side flow passage 12 is formed by an opening and closing valve body 15. In a driving block 10b, a driving rod 19 for driving opening and closing of the opening and closing valve body 15 is provided. A pressure fluctuation absorption chamber 33 communicating with the secondary flow passage 12 is sectioned by a diaphragm 32. An elastic deformation amount of the diaphragm 32 at the time when the pressure fluctuation absorption chamber 33 expands is restricted by a stopper 37.
