又は第３項記載の圧力上昇時間調整装置。[Claims for Utility Model Registration] 1. The piston is reciprocated by intermittent energization of the electromagnetic coil to change the volume of the pump chamber, and this change in the volume of the pump chamber cooperates with the suction valve and the discharge valve. In an electromagnetic pump configured to pump liquid, a plunger is slidably inserted into a cylinder, and the interior of the cylinder is connected to a high-pressure passage downstream of the discharge valve, and a high-pressure side chamber is connected to a high-pressure passage upstream of the suction valve. The high-pressure side chamber and the low-pressure side chamber communicate with each other through an orifice formed in the plunger, and the plunger is pressed by a main spring to the high-pressure side chamber, and the high-pressure side chamber is connected to a low-pressure passage on the side. A first valve is provided that blocks communication between the high-pressure side chamber and the low-pressure side chamber until movement of the plunger due to an increase in pressure in the side chamber exceeds a predetermined value, and a first valve is provided that blocks communication between the high-pressure side chamber and the low-pressure side chamber until movement of the plunger due to an increase in pressure in the high-pressure side chamber is prevented. A second valve is provided that allows communication between the low pressure side chamber and the low pressure passage until the pressure reaches a maximum, and when the pressure reaches the maximum, allows a small amount of liquid to leak and blocks communication between the low pressure side chamber and the low pressure passage. The second valve includes a movable seat portion formed near the periphery of the end face of the plunger facing the low-pressure side chamber, and a fixed portion provided opposite to the movable seat portion so that the movable seat portion can come into close contact with the movable seat portion. A pressure rise time adjusting device comprising a seat portion. 2. The pressure rise time adjusting device according to claim 1, wherein the fixed seat portion is provided in a body portion that is integrated with the pump main body. 3. The pressure rise time adjusting device according to claim 1 or 2, wherein the fixed seat portion is made of a packing made of a soft material. 4. The pressure increase according to claim 1, 2, or 3 of the utility model registration claim, characterized in that the first valve is housed in a valve case, and the valve case and cylinder are fitted together. Time adjustment device.
