Claims

[Claims for Utility Model Registration] (1) A motor is used to send pressurized medium to a pressure storage section, and a discharge hole for discharging the pressurized medium from the pressure storage section and a valve for opening and closing the hole are provided. The valve is interlocked with the rotating shaft of the motor and closes during forward rotation;
A pressurizing pump configured to open when the rotation is reversed, and a driving shaft that transmits the rotation of the motor;
A pressurizing pump comprising a driven shaft that transmits the movement of the driving shaft to the valve to open and close the discharge hole, and these are configured to interlock with each other via a coil spring mechanism. (2) The coil spring mechanism constitutes a clutch mechanism in which the driving shaft and the driven shaft are interlocked by tightening the coil spring, and when a force that stops rotation is applied to the driven shaft, the coil spring is loosened and the interlocking is released. A pressurizing pump according to claim 1 of the utility model registration claim. (3) The coil spring mechanism consists of one intermediate shaft and two coil springs in which the winding direction is reversed and this intermediate shaft is connected to a driving shaft and a driven shaft.Claim 1 of the Utility Model Registration Claim Or the pressure pump described in item 2. (4) The driven shaft is combined with a movable element that linearly moves toward and away from the exhaust hole by its rotational motion to open and close the valve.Claims 1 to 3 of the claims for registration of a utility model. The pressurized pump described in any of the above. (5) A utility model registration request in which the mover converts the rotational motion of the driven shaft into linear motion by engaging the protrusion provided on the mover with the spiral groove provided on the peripheral surface of the driven shaft. A pressurized pump according to range 4. (6) The pressurization according to claim 4 of the utility model registration claim, wherein the mover converts the rotational motion of the driven shaft into linear motion by screwing with a screw formed on the peripheral surface of the driven shaft. pump. (7) The pressurizing pump according to any one of claims 1 to 6, wherein the coil spring is formed of a square wire.
