A rotary pump comprising a pump unit having a pump and a motor unit separated from the pump unit and having a motor for driving the pump. The rotary pump further comprises a watertight housing enclosing the motor and including a non-magnetic wall made of material which permeates magnetism, an input section attached to the pump, an output section attached to the motor and opposing the input section, with the non-magnetic wall interposed between the output section and the input section, and at least two magnets, one of which is fixed to that surface of the output section which opposes the input section, and the other of which is fixed to that surface of the input section which opposes the output section.

An electromagnetically reciprocating apparatus includes a piston assembly which is driven by an electromagnet repeating magnetization and demagnetization and a compression coil spring so as to reciprocate a front and rear pistons of the assembly in a front and rear cylinders. An air hole is formed in the rear cylinder to communicate a sealed inner space partitioned in the cylinder by the rear piston with an atmosphere. A valve is mounted on the air hole to adjust a resonance frequency of the vibration system of the apparatus.

A pneumatic body treating device 12 of a pneumatic body treating apparatus includes a plurality of airtight chambers 16, 18, 20, and 22 to and from which pressurized air is supplied and discharged, a hose 21 having a connecting end connectable to a pressurized air source 148 of a pneumatic body treating apparatus body 14, and a plurality of electromagnetic valves 24, 26, 28, and 30 which are connected between the hose and the airtight chambers 16, 18, 20, and 22, respectively, and which supply pressurized air from the hose 21 to the corresponding airtight chambers and discharge the pressurized air from the corresponding airtight chambers. With this arrangement, it is possible to reduce the number of connecting hoses for supplying pressurized air to the pneumatic body treating device which, when used, is worn around the upper limbs and the lower limbs.

A gas separation/extraction apparatus comprises a tank for separating and extracting a specific gas element from a gas mixture, the tank containing an adsorbent for adsorbing the gas element from the gas mixture, a pump having a cylinder and a piston housed therein, the pump being adapted to alternately pressurize and decompress the inside of the tank as the piston reciprocates, a first three-way solenoid valve connected between an exhaust port of the tank and a suction port of the pump, a second three-way solenoid valve connected between a discharge port of the pump and the suction port of the tank, and a pressure balance unit connected between the second three-way solenoid valve and a suction port of the tank, and adapted gradually to eliminate a difference in pressure between the tank and the pump as the tank is switched from a decompressed state to a pressurized state.
摘要:
An electromagnetic reciprocating fluid device in which a movable member is equipped with permanent magnets, resists a torque rotating the movable member about an axis thereof in the reciprocating direction. The electromagnetic reciprocating fluid device has a pair of electromagnets facing each other, and permanent magnets disposed in a space between the opposed electromagnets and held by a movable member. When an alternating current is applied to coils formed in the electromagnets, a magnetic force is generated between the electromagnets and the permanent magnets, whereby a driving force for reciprocation is applied to the movable member. One end of the movable member is connected to a piston of a first piston-cylinder assembly, while the other end is connected to a piston of a second piston-cylinder assembly. The first and second piston-cylinder assemblies are arranged such that an axis line of the first piston-cylinder assembly and an axis line of the second piston-cylinder assembly are non-coaxial and vertically offset from an axis of the movable member.

An electromagnetic reciprocating fluid apparatus includes a magnetic circuit device in which magnetic pole members project inward from an annular magnetic circuit member so as to oppose each other. The magnetic pole members and the annular magnetic circuit member have a uniform thickness. First and second additional annular magnetic circuit members are set on both sides of the annular magnetic circuit member to constitute a part of the magnetic circuit device, thereby minimizing the increase in magnetic reluctance due to magnetic flux concentration at the joints between the magnetic pole members and the annular magnetic circuit member.
