Abstract: A rocking piston type compressor is provided with a piston rod, a lip ring, and a ring holding member. The lip ring includes a center portion fixed by the ring holding member, and a lip portion upwardly extending around the center portion along a periphery of the ring holding member. The ring holding member includes a flange portion covering at least a part of an upper end surface of lip portion. A back pressure introducing portion is provided in a part of the flange portion.

Abstract: In a rocking piston type compressor, a piston rod 11 is rockingly slidable within a cylinder 10. The compressor is provided with a lip ring 20 and an expansion member 30. The lip ring 20 is configured to seal between the cylinder 10 and piston rod 11. The lip ring 20 is provided on a leading end portion 13 of the piston rod 11 and includes a bottom portion 21 in a circular plate shape and a lip portion 22 extending from an entire peripheral edge of the bottom portion 21 to an upper side in a height direction. The expansion member 30 is provided on an inside of the lip portion 22 and configured to outwardly expand the lip portion 22 at a side of an upper portion in the height direction of the lip portion.

Abstract: An air compressor is provided. The air compressor includes a compression mechanism including a cylinder to generate compressed air, a motor provided to drive the compression mechanism, an inverter board including an inverter to control a rotation of the motor, two elongated tanks provided to store the compressed air generated by the cylinder, and a fan rotated by the motor to supply cooling air. The tanks are arranged below the cylinder and the motor, and the inverter board is arranged between the cylinder and the tanks.

Abstract: A valve body of each of low and high-pressure couplers is urged in a close direction in to a supply side of a partition. A stem that penetrates through an opening portion and projects into the receive side is connected to the valve body. A cylinder portion is formed on the receive side of the partition. A locking mechanism is provided in a vicinity of an end portion of the cylinder portion. A movable sleeve having an annular projecting portion is provided on an inside of the cylinder portion. Each of low and high-pressure plugs has an annular projecting surface that can engage with the annular projecting portion, a flange that engages with an end portion of the cylinder portion, and an engaging portion that can engage with the locking mechanism.

Abstract: A valve body (12) of each of low and high-pressure couplers (1,2) is urged in a close direction in to a supply side (A) of a partition (11). A stem (13) that penetrates through an opening portion and projects into the receive side (B) is connected to the valve body (12). A cylinder portion (18) is formed on the receive side (B) of the partition (11). A locking mechanism (22) is provided in a vicinity of an end portion of the cylinder portion. A movable sleeve (23) having an annular projecting portion (26) is provided on an inside of the cylinder portion. The movable sleeve (23) is urged to a lock releasing position where a lock of the locking mechanism (22) is released. Each of low and high-pressure plugs (3,4) has an annular projecting surface (34) that can engage with the annular projecting portion (26), a flange (33) that engages with an end portion of the cylinder portion (18), and an engaging portion (32) that can engage with the locking mechanism (22).

Abstract: A socket portion (11) capable of mounting either of a high pressure exclusive plug and a normal pressure exclusive plug is formed at one end of a coupler (6). In the coupler (6), an opening/closing valve (18) for opening and closing a flow path of a compressed air is provided, and a pressure reducing valve for reducing an air pressure to a predetermined pressure value proximate to substantially an upper limit value of an operating pressure region of a normal pressure tool by controlling the opening/closing valve (18) is formed. Thereby, when the normal pressure exclusive plug (P1) is mounted, air the pressure of which is reduced by the pressure reducing valve is supplied to the normal pressure exclusive plug (P1).
