PROBLEM TO BE SOLVED: To provide a liquid substance ejector having a poppet valve body moving up and down corresponding to an action member in a pump cylinder, wherein the inhibition of the action of the valve due to the press-fitting of a coil for energizing the action member to a part of the poppet valve body is avoided.SOLUTION: A coil spring C is interposed between a plurality of engaging projected pieces S provided in the inner peripheral surface lower part of a pump cylinder and the poppet valve body provided in the pump cylinder in corporation with the action member. A part facing the same peripheral direction as the spiral direction L at least from a base end part 48 of the coil spring C to the tip end part in the upper surface of the abutting projection G which the poppet valve body has is made as a first slide inclination surface A1 inclined to the direction making a right angle with the spiral direction L and the first slide inclination surface A1 faces the end surface of the base end part 48 obliquely to be in contact with the base end part. |
