Japanese Piston Ring push continuously variable valve actuator

Japan Piston Rings Co., Ltd. exhibited "Continuous Variable Valve Actuater (CVVA)" at the 39th Tokyo Motor Show (open to the public from October 22 to November 6, 2005) , The valve can be continuously variable inlet valve on the engine. "Dramatically reduces pumping losses and improves fuel efficiency" (the company). Ordinary engines are through the throttle to adjust the intake and exhaust opening and closing. If this is the case, the low intake will reduce the amount of suction by closing the valve, which in turn will create drag due to the negative pressure in the intake manifold, resulting in losses. This is the pump loss. The engine equipped with CVVA does not open and close the throttle, but by virtue of the valve to adjust the amount of inhalation. A structure in which the first and second swing arms are transmitted by the motion of the suction cam and the accelerator connected to the second swing arm moves up and down. A "lever" is provided on the upper part of the second arm, and the tip of the lever is rotationally moved on the upper part of the second arm. Lever control lever position for the second swing arm pivot, so as to adjust the amount of valve lift. This configuration is envisaged to reduce the amount of intake air by reducing the amount of valve lift during low-speed rotation, and to increase the amount of intake air by increasing the amount of valve lift during high-speed rotation. The lever itself is driven by an actuator that uses a ball screw with a rotary motor. The company believes that for straight-line cylinder engines, for example, while all cylinders are equipped with control levers, only one actuator is required to drive all levers. However, "can not be directly built in the engine, you need to further reduce the size."

Rotary Tablet Press

Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.

The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.

Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.

With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
