Abstract: A restarting device of a pump change-over valve in a pump is provided, in which the pump includes; a pump main body 1 and a change-over valve 2. The change-over valve 2 is provided with a pair of pressure chambers 31 and 32 formed at respective ends on the back face sides of a valve body 23. The driving fluid is supplied into the chambers to induce a pressure difference to switch the direction of movement of the valve body 23. Also, the pump main body 1 is provided with a balancing valve 49 whose end portions 49A and 49B face driving chambers 4A and 5A, respectively. If the change-over valve 2 malfunctions and the pressures in the two driving chambers 4B and 5B are balanced, the balancing valve 49 is held in an intermediate position and will then induce a pressure difference between the two pressure chambers 31 and 32.
