PURPOSE: To ensure fixed volume ejection performances without using a coil spring by a method wherein a valve stem resting on a stem rubber provided on a part of a valve housing is supported by an elastic supporting part which is formed integrally with a part of the valve housing. ;CONSTITUTION: A valve stem 2 resting on a stem rubber 3 disposed on a valve housing 4 is supported by an upstanding elastic valve stem supporting part 9 which is formed integrally with the housing 4. And a structure capable of fixed volume ejection is disposed in the housing 4. On the other hand, a part of a mountain cap 1 and a part of the housing 4 are formed integrally with each other through synthetic resin. And the structure capable of ejecting at fixed volume is constituted from, for example, a liquid feed pipe 10, a vertical hole 15 and a cross hole 16 each being connected to an ejection port, and a liquid feed port 19. Consequently, excellent properties capable of ejecting at fixed volume can be ensured without using a conventional metal coil spring.;COPYRIGHT: (C)1994,JPO
