ンジン負荷応動式自動開閉装置。[Claims for Utility Model Registration] 1. A negative pressure system having a first chamber M1 communicating with the intake manifold N of the engine E through a conduit, and a second chamber M2 separated from the first chamber M1 by a diaphragm. actuator V and the diaphragm 5
An engine load-responsive automatic opening/closing device comprising a spindle 8 with one end attached to the second chamber M2 and the other end protruding outside from the second chamber M2 , and a switch part SW that is turned on and off by reciprocating linear motion of the spindle 8, The engine load-responsive automatic opening/closing device is characterized in that the switch section SW is constituted by a power switch S that turns on and off an electromagnetic clutch C that connects the engine E and a load member that applies a load to the engine E. 2. The switch portion SW includes a switch sliding shaft S1 provided coaxially with the spindle 8, and a sliding shaft spring S2 that resiliently repels one end of the switch sliding shaft S1 toward the tip of the spindle 8. , a regulating member S that regulates the amount of protrusion by this sliding shaft spring S2.
5. The engine load-responsive automatic opening/closing device according to claim 1, further comprising a power switch S that is turned on and off by displacement of the other end of the switch sliding shaft S1. 3 The switch part SW is configured such that a gap K is created between the spindle 8 and the switch sliding shaft S1 by the membrane movement of the diaphragm 5 when the vacuum suction force in the intake manifold N increases when the load decreases. A photoelectric switch PS is provided so as to face each other between this gap K, and this photoelectric switch PS
The engine load responsive type according to claim 2, characterized in that when the light is not blocked by the switch sliding shaft S1, a display member that displays the operation of the member that increases the vacuum suction force is turned on. Automatic opening and closing device. 4 The negative pressure actuator V is connected to the first chamber M.
2. The engine load-responsive automatic opening/closing device according to claim 1 , further comprising a spring member 4 that is resilient so as to project the spindle 8 to the outside, and an adjustment screw 1 that adjusts the resilient force of the spring member 4. . 5 The switch section SW is a first micro switch B that is turned on and off by the tip of the spindle 8.
1 and a second microswitch B2 that is turned on and off by the side surface of the spindle 8, the first microswitch B1 is connected to the power switch S, and the display member is connected to the second microswitch B1. The engine load responsive automatic opening/closing device according to claim 2.
