Abstract
An electric pump includes a cylinder, a piston, a motor, and a discharge valve. The cylinder includes a valve port and a discharge port, which is in communication with the valve port. The discharge valve opens and closes the valve port. When the piston is moved forth to narrow a void in the cylinder, air is compressed in the cylinder. The discharge valve opens when operated by the piston that moves forth. The discharge valve opens and discharges compressed air from the valve port so that fluid including air is discharged from the discharge port.
