The relay valves 22 are provided with diaphragms 22f that are disposed so as to project laterally from pistons 22e and supporting the pistons 22e while allowing the piston to reciprocate. The two relay valves 22, 22 are disposed in horizontal alignment with a space therebetween such that the diaphragms 22f thereof are mutually adjacent. The variable load valve is disposed in a position between the two pistons 22e and away from a position where the diaphragms 22f are mutually adjacent.",
