Abstract

PURPOSE:To make it hard to be subjected to the influence of the vibration of an engine by installing a control valve for feeding and discharging pressure oil into an from the hydraulic chamber of a hydraulically operating type valve stopping means, in an inclined posture in which said valve is inclined to a little extent in the vertical direction from a horizontal posure in the right-left direction, nearly parallel to a crank shaft. CONSTITUTION:A valve for the air sucking and discharging system of engine 1 is arranged in such a way that a stopped condition, in which the valve does not follow the movement of a valve cam, can be selected through the operation of a valve stopping means. In this construction, a control valve 3 for feeding and discharging pressure oil into the from and the hydraulic chamger of the valve stopping means installed in a cylinder head 2, is mounted in an inclined posture in which its valve case 9 is inclinined to a little extent in the vertical direction from a horizontal posture in the right-left direction parallel to a crank shaft. The angle of inclination is desirably about 25 deg.. Thereby the vibration of the engine acting on a spool valve 10 in the control valve 3 can be reduced, smaller springs, etc. can be employed, which are provided to protect the device from an inadvertent operation, and the device can be miniaturized as a whole.

するを要して好ましくない。Conventionally, as a device of this kind, for example, as shown in the first diagram, a hydraulically operated valve stop means d has a hydraulic chamber C into which pressure oil is introduced and extracted into a cylinder spatula (Ta) at the top of the engine through a control valve. The valves of the intake and exhaust system of the engine can be freely switched to a rest state in which they are not driven by the valve cam, and the valve is provided with a spool valve f that is slidable along the longitudinally extending valve housing e. A type was proposed in which the control valve was constructed into a type and fixedly mounted on the head a, but in this case, the control valve was parallel to the crankshaft of the engine in the valve housing e as shown in the figure. Generally, the valve is installed in a horizontal position in the left-right direction, and in such a valve, the vibration of the engine is applied to the valve, which tends to cause an inadvertent switching operation. To further explain, if the engine is a 4-recycle inline 4-cylinder engine, for example,
In addition to producing large vibrations in the vertical direction, it also produces large vibrations in the left and right directions, that is, in the direction parallel to the crankshaft. This is undesirable because it is necessary to increase the elasticity of the spring or the magnetic force of the operating solenoid in order to prevent this.

する。The object of the present invention is to provide a device that reduces such inconveniences as much as possible, and has a hydraulic chamber in the cylinder head at the top of the engine, into which pressure oil is introduced and extracted via a control valve. A hydraulically actuated valve stop means is provided to freely switch the valves of the intake and exhaust system of the engine to a rest state, and the control valve is placed in a longitudinally extending cylindrical valve housing, and a spool valve is slid along the valve housing. The control valve is of a freely movable type, and is characterized in that the control valve is mounted in the valve housing in an inclined position slightly tilted in the vertical direction from a horizontal position in the left-right direction substantially parallel to the crankshaft of the engine. .

るようにした。Figures 2 to 5 show one example, where ill is an engine mounted on the body of a two-wheeled motor vehicle, (2) is the cylinder head at the top, and the head hydraulic chamber (4) is A hydraulically actuated pulp stop means (5) is provided, so that the valves (6) of the intake and exhaust system of the engine [11] can be freely selected into a rest state in which they are not driven by the valve cam (7). To explain this in more detail with respect to what is shown, the stop means (5) may include a portion of the rocker Y-arm (8a) which engages the valve cam (7), as shown in FIGS. ) and the valve cam (the other side of the rocker arm (8b) that does not engage the force), and according to the introduction of pressure oil into the hydraulic chamber (4), the shift bin (5) is pressed by the pressure oil and passes through the front to connect the double-ended hook arms (8a) and (8b) to each other as shown in the sixth figure, for example. The control valve (3) is pushed back by a spring (5a) and acts to separate the two-ended lock arms (8a) (813) from each other.Furthermore, the control valve (3) has a longitudinally extending cylindrical valve housing. The spool valve (101) shall be of the type provided with a spool valve (9) which can be slid freely along the inside thereof, and shall be fixed to the rear part of the cylinder head (2). The spring (ill) switches between one side and the operating solenoid (+21) slides between the two, and an accumulator 03 is provided on the side of the solenoid (+21) and approximately parallel to the solenoid.

For example, as shown in FIG. 5, the control valve (3) is changed from a horizontal position parallel to the crankshaft of the engine (1) to an inclined position slightly tilted in the vertical direction in its valve casing (9). Made it possible to install it. In this case, the angle of inclination in the vertical direction is preferably about 25 degrees.
