Description of the invention: . [Technical field to which the invention pertains] This creation is a reciprocating thruster. It is a combination of an axial hollow piston and a check valve member. When the piston reciprocates, the water is pushed backwards and ejected. The reaction force of the water jet is used to move the carrier. [Prior Art] Conventional water surface and water downloading propellers are impeller type. The way it is applied is to use the engine or motor to drive the propeller's main shaft to rotate, which in turn causes the propeller to rotate to push the water. The reaction of the water causes the carrier to move. This method will form a wake region behind the thruster shaft. The formation of the wake will not only affect the forward speed of the vehicle, but also cause noise and hole. [Summary of the Invention]: This creation uses a reciprocating piston to make a new propeller design. The goal is to eliminate wake and its induced noise and pitting problems. _ The designed thruster consists of a housing with a accommodating space, the front end opening is the water inlet of the propeller, and the opening at the rear end is the water outlet nozzle. The outer casing is placed with a piston, and the outer casing is provided with electromagnetic components. The piston is hollowly formed in the axial direction, wherein the empty pipe is provided with a check valve member, and magnetic materials are disposed at both ends of the piston. The electromagnetic component is externally connected to a power source to generate a magnetic field that alternates between positive and negative. When current is passed through the electromagnetic element, the magnetic field exerts a repetitive push-pull force on the magnetic material, causing the piston to reciprocate within the pusher. When the piston reciprocates, the water is propelled from the propeller 1298307 nozzle through the piston inner pipeline to the propeller outlet nozzle by using the outer valve and the check valve of the piston itself. The reaction force of the water nozzle bundle advances the carrier in the opposite direction. [Embodiment] Please refer to the first, second, third, fourth, fifth and sixth figures. The new invention is a reciprocating propulsion using a magnetically driven piston. The body (ίο) includes a propeller housing (n), a water inlet (12), a water inlet check valve member (丨3), a water outlet nozzle (14), a hollow piston (15) including a check valve, and a piston stop. Return valve member (16), magnetic material (17), electromagnetic component (18). The propeller housing is an accommodation space having a water inlet at the front end and a water outlet at the rear end. The water inlet guides the flow of water into the orifice of the propeller. The inlet check valve member is a valve member that controls the flow of water into the propeller. A water outlet that directs the flow of water away from the orifice of the pusher. The hollow piston with the check valve has a unidirectional pipe inside, which enables the living base to guide and push the water flow, and the magnetic materials are arranged at both ends. The check valve member of the piston is installed at one end of the hollow pipe of the piston to control the valve member whose water flows in one direction inside the piston. A magnetic material that is attached to both ends of the piston and that generates a repulsive or attracting force with the electromagnetic element, causing movement of the piston. An electromagnetic component, which is an element that overlies the outer casing of the propeller, generates a magnetic force in the direction of movement of the piston during load current to drive the piston. , 6 1298307 This creation system drives a piston (15) in a propeller through an electromagnetic element (18) overlying the outer casing (u) of the propeller, and magnetic material (17) is mounted at both ends of the piston. When a current passes through the electromagnetic element (18), a magnetic field of a changing direction is generated, which is opposite to the magnetic material (17).
