Abstract
An electromagnetic valve, a circuit board on which a control circuit for controlling the electromagnetic valve is mounted, and a cover for covering the electromagnetic valve and the circuit board are installed on a device-attaching surface of an adapter plate disposed at one end in a direction of an axial line of an air cylinder, in a manner so as to be housed within a surface area of the device-attaching surface, and an output port of the electromagnetic valve and a pressure chamber of the air cylinder are allowed to communicate with each other through an air through-hole provided in the adapter plate.
Claims14
An air cylinder apparatus comprising:
- an air cylinder comprising a piston operating via action of pressurized air, and pressure chambers that cause the pressurized air to act on the piston, in an inside of a cylinder housing;
- and
- a control device that controls the air cylinder while attached to the cylinder housing,
- wherein the control device is constructed by attaching an electromagnetic valve that supplies and discharges the pressurized air to the pressure chambers, a circuit board on which a control circuit that controls the electromagnetic valve is mounted, and a cover that covers the electromagnetic valve and the circuit board, to a device-attaching surface of an adapter plate disposed at one end in a direction of an axial line of the cylinder housing, which faces the direction of the axial line, and
- wherein the electromagnetic valve is fixed to the device-attaching surface of the adapter plate, and output ports of the electromagnetic valve and the pressure chambers are allowed to communicate with each other through respective air through-holes provided in the adapter plate,
- wherein the circuit board is attached to an inside of the cover and occupies a position adjoining the electromagnetic valve,
- wherein the cover is detachably attached to the adapter plate together with the circuit board, and
- wherein coil terminals of the electromagnetic valve are connected to circular terminals of the circuit board in a plug-in manner when the cover is attached to the adapter plate.
