Title: Variable-compression ratio engine
Inventor: NAGAO AKIO
IPC: F02D15/04
Filed: 1986-12-19
Abstract: PURPOSE:To adequately perform the necessary control at the switching time of the actual compression ratio by judging the switching of compression ratios of cylinders in response to the quantity or the operating oil pressure based on the signal from an oil pressure sensor provided on the operating oil passage of a compression ratio-variable mechanism. CONSTITUTION:The oil pressure of an oil pump 22 feeding the oil of an oil pan 21 to various sections of an engine is utilized to change the relative position of a piston 3 with respect to a connecting rod 23, thereby the compression ratio of the engine is changed. Therefore, a hydraulic solenoid valve 25 is provided as a compression ratio changing means controlled by a controller 27 on an oil line 24 for changing the compression ratio. In this case, an oil pressure sensor 26 is provided on the oil line 24. The controller 27 judges the switching of compression ratios of cylinders in response to the quantity of the operating oil pressure based on the signal from the oil pressure sensor 26. Accordingly, the necessary control is performed with a good timing at the switching time of the actual compression ratio.

Title: Pneumatic operating valve
Inventor: KAZAMA YOICHIRO
IPC: F16K31/122
Filed: 1990-11-13
Abstract: PURPOSE:To directly confirm the opening/closing state of an operating valve by installing an approach switch in parallel to the axial direction of a cylinder and detecting the closing of a piston to the approach switch, accompanied with the shift of the piston. CONSTITUTION:An approach switch 230 is fixed in parallel to the axial direction in the vicinity of the outer periphery of a cylinder 210, and the top edge of the approach switch 230 is separated by the distance S from the upper surface of a piston 200. Since a pneumatic operating valve is opened and closed within the elasticity range of a diaphragm 110, the stroke between opening and closing can not be set large. If an article is brought close, the approach switch 230 is turned ON, while if the article is separated, the approach switch 230 is turned OFF, and the distance differs according to the kind of the article. When the piston 200 is made of steel for example, the approach switch 320 is turned ON within a range of about 1mm or less, and turned OFF over this distance, and the above-described distance S is properly set to 1.3mm or so. Accordingly, accompanied with the shift of the piston 200 for opening and closing, the approach switch 230 detects the closing of the piston 200, and the direct opening and closing state of the operating valve can be confirmed.
