摘要： PURPOSE:To make the start of an engine ever so smooth, by making a low speed cam so as to be selected in time of turning off a key switch, in case of a device changing the on-off timing and lift of a valve in a way of selectly using both high and low speed cams in order. CONSTITUTION:A controller detects a key switch 8 being cut off and after the cutoff, for a limited time, it has a delay circuit 73 delaying the cutoff of power supply from a battery 9 and a selecting signal control circuit 7 emitting a low speed cam selecting signal in order to shift a cam follower 22 to the low speed side during operation of the delay circuit 73. When the key switch 8 is turned off, the cam follower is forced to slidably make contact with a low speed cam regardless of engine speed just before the cutoff, so that engine starting takes place in a smooth manner.

摘要： PURPOSE:To reduce power loss of a pump in a resistance valve unit for feeding oil not supplied to a cylinder of a variable valve mechanism to various sliding parts of an engine, by employing such an arrangement that the valve opening pressure is variable and a valve of the resistance valve unit is opened at a low pressure when the engine speed is low. CONSTITUTION:The operation of an intake valve and an exhaust valve is controlled by feeding oil to a hydraulic cylinder 50 and using a high-speed cam 61 or a low-speed cam 62 selectively. Oil not supplied to the hydraulic cylinder 50 is passed through a resistance valve unit 11 and supplied to various sliding parts of an engine via a passage 12. A valve body 13 of the resistance valve unit 11 is opened depending on the pressure in a piston chamber 17. When the hydraulic pressure is lowered and a spool valve 21 is moved to the left, supply of oil to the piston chamber 17 is stopped, so that the valve body 13 is opened even at a low pressure due to drop of pressure in the chamber 17. Therefore, it is enabled to reduce the power loss of a pump.

摘要： PURPOSE:To vary rapidly the condition of valve opening and closing by a method wherein an upstream side of a resistance valve unit provided at the halfway of an oil supplying passage from an oil pump is communicated to a variable valve mechanism, and a bypass line of a resistance valve is opened or closed with a downstream side oil pressure. CONSTITUTION:A resistance valve unit 20 is provided on an oil supplying line 5 from an oil pump 3, a variable bypass valve 80 is arranged on bypass lines 70, 71. When the condition of valve opening and closing is varied, a change-over valve 61 is changed-over, an oil inside of an oil supplying pipe 5 is supplied into an oil cylinder device 44 of a variable valve mechanism 30. At this time, because of the pressure inside of the oil supplying pipe 5 decreases rapidly and the resistance valve unit 20 is closed, the whole quantity of oil is supplied into the oil cylinder device 44, the condition of valve opening and closing is rapidly varied. When the variable bypass valve 80 is opened due to the decreasing of pressure inside of an oil supplying pipe 92, the opening action is delayed certain time caused by the providing of a throttle 91.

摘要： PURPOSE:To prevent impact noise created when a plunger changes the operating characteristics of a valve according to oil pressure by disposing an impact attenuating member at the position where the plunger's changing operation is terminated. CONSTITUTION:Changeover of the operating characteristics of a valve is attained by axially displacing a cam shaft 1 so that either cam 5 or 6 can rock a rocker arm 9. The displacement of the cam shaft 1 is controlled by a plunger 27 which is disposed inside a fixed member 21 and moved in response to the pressure oil supplied according to the action of solenoid valves 50 and 51. Both impact attenuating members 28 and 29 are positioned inside the fixed member 21 to prevent impact noise created from the plunger 27. When the plunger 27 goes to its terminal position, a catching member 40 is engaged into a catching hole 42 to prevent movement of the plunger 27. Said engagement is released under control of a cam 8 and the movement of the plunger 27 will not be made while the valve is lifted.

摘要： PURPOSE:To enable a rapid change-over operation by a method wherein a means for exerting an elastic force on a hydraulic piston in only one direction is provided as a driving means for a rocker arm or the like, in a system wherein valve operating conditions of intake, exhaust and other valves can be varied in accordance with the operating condition of an engine. CONSTITUTION:When operating an engine at high speed, a change-over valve 1 is changed over to the position shown and the piston 6 in a hydraulic cylinder 4 is moved leftwards by a hydraulic oil fed from pump 50. By this, the rocker arm 17 is maintained at such a position that a ball 23 receiving the force of a spring 25 is engaged with a circumferential groove 24a of a rocker shaft 21, and a cam follower 18 is engaged with a high-speed rotating cam 16a on a cam shaft 15. Therefore, a valve lifter 26 is operated at a high speed through arms 17, 20 in accordance with the rotation of the cam 16a. In this device, in order to enable a rapid change-over from the cam 16a to a low-speed rotating cam 16b, a forcing spring 14 is provided for the shaft 7 to force the shaft 7 rightwards.

摘要： PURPOSE:To prevent the movement of a plunger as well as attain quick changeover of the operating characteristics of a valve by directly moving the plunger by the hydraulic method and, on the contrary, deeply engaging a catching member, or the preventive means for the movement of the plunger, with said plunger to restrict any movement thereof when the valve is lifted. CONSTITUTION:Changeover of the operating characteristics of a valve is attained by axially displacing a cam shaft 1 so that either cam 5 or 6 can rock a rocker arm 9. The displacement of the cam shaft 1 is controlled by a plunger 27 which is disposed inside a fixed member 21 and moved in response to the pressure of oil supplied according to the action of solenoid control valves 50 and 51. Catching holes 42 and 43 are formed in the fixed member 21 and the engagement of a catching member 40 in either the hole 42 or 43 prevents the movement of the plunger 27. The depth at which the catching member 40 is engaged therewith is regulated by a cam 8. When the valve is lifted, the engagement is made deeply to prevent any movement of the plunger 27, hence preventing any evidence of damages on the cam or the rocker arm.
