|20140123845||RODLESS POWER CYLINDER - A rodless power cylinder includes a cylinder body, a piston assembly adapted to reciprocate in the cylinder body, a magnet mounted at each of the two ends of the piston assembly, a valve mounted at each of the two ends of the cylinder body for guiding a flow of air or fluid in and out of the cylinder body to cause the piston assembly to reciprocate, a magnetic sensor mounted in a sensor mounting groove at each of the two valves for sensing the position of the respective magnet, a movable member mounted around the cylinder body and coupled to the piston assembly by a magnetic force for synchronous reciprocating motion||05-08-2014|
|20130098240||PRESSURE CYLINDER HAVING A HIDDEN LOOP DESIGN - A pressure cylinder includes a pressure-boosting member set, an actuation member set, and a cylinder body, which defines two transversely extending air inlets, two transversely extending air outlets and two air passages respectively axially connected between the two air inlets and the two air outlets for allowing an applied compressed gas to flow through the two air inlets and the two air passages and the two air outlets into an air chamber in the cylinder body to move the pressure-boosting member set and the actuation member set in an oil accumulation chamber in the cylinder body. The hidden loop design for guiding the applied compressed gas does not require any extra pipelines and connectors, avoiding pipeline deterioration or connector loosening problems.||04-25-2013|
|20130098238||OIL-GAS SEPARATED PRESSURE CYLINDER - An oil-gas separated pressure cylinder, which combines a hydraulic cylinder, a pneumatic cylinder and a pres-pressure cylinder, and keeps the applied compressed gas and the storage hydraulic fluid apart, maintaining the quality of the hydraulic fluid and saving the hydraulic fluid replacement cost. When the applied compressed gas enters the pre-pressure cylinder to move a pre-pressure cylinder piston in forcing the storage hydraulic fluid out of an oil storage space of the pre-pressure cylinder into an oil storage space in the hydraulic cylinder, a hydraulic cylinder piston of the hydraulic cylinder is then forced by the hydraulic fluid to move a hydraulic cylinder piston rod against the workpiece, and then a pneumatic cylinder piston rod of the pneumatic cylinder is forced into the oil storage space of the hydraulic cylinder to enhance the pressure at the hydraulic cylinder piston rod against the workpiece.||04-25-2013|
|20120017758||PRESSURE CYLINDER WITH OIL STORING FUNCTION - A pressure cylinder includes a first cylinder body having accommodated therein a piston. a second cylinder body defining therein a first passage vertically connected to the first cylinder body, an oil storage chamber vertically connected to the first passage, a second passage vertically connected to the oil storage chamber and a pressure chamber vertically connected to the second passage and having a cross-sectional area smaller than the oil storage chamber, and a piston rod inserted through the first passage of the second cylinder body in an airtight manner and having its one end connected to the piston and its other end movable by the piston between a first position in the oil storage chamber and a second position in the pressure chamber to add a pressure to the hydraulic oil in the pressure chamber and to let the hydraulic oil in the oil storage chamber be supplied to the pressure chamber to make up any hydraulic oil loss, maintaining the output.||01-26-2012|
|20100143025||MULTI-PURPOSED PNEUMATIC TUBE CONNECTOR - A multi-purposed pneumatic tube connector, which is incorporated in a pneumatic system to create a second passageway, includes a main member and an electromagnetic valve. The main member has a main tunnel, a first tunnel, a second tunnel, an inter-tunnel, and a sub-tunnel. The second tunnel is normally communicated with the main tunnel. The inter-tunnel is communicated with the main tunnel, in which a control end of the electromagnetic valve is inserted. The inter-tunnel is communicated with the first tunnel through the sub-tunnel, and the electromagnetic valve may control the communication of the main tunnel and the first tunnel.||06-10-2010|
|20100139411||DIGITAL PRESSURE SENSOR - A digital pressure sensor, which is mounted on a pressure controller of a pneumatic tube system, includes a casing including a control circuit, which has a pressure sensing unit, therein, a display, which has a plurality of displaying units for showing numerals or icons, on a front side connected to said control circuit, and a connection tube on a bottom thereof for communication with a connection tube of the pneumatic tube system that said pressure sensing unit of said control circuit senses a pressure in the tube via said connection tube; and a battery set received in said casing and electrically connected to said control circuit.||06-10-2010|
