Abstract
The utility model discloses a cylinder cover gasket throttling assembly. The cylinder cover gasket throttling assembly comprises a water hole, and a notch communicated with the water hole and formed on the edge of the water hole. The interior of the notch is connected with a clamping hooked bar. The cylinder cover gasket throttling assembly further comprises a throttling sheet in clearance fit with the interior of the water hole. A throttling hole with a diameter smaller than that of the water hole is formed in the throttling sheet. The throttling sheet is connected with a clamping hook matched with the notch and capable of being clamped onto the clamping hooked bar. The throttling sheet in clearance fit with the interior of the water hole plays a throttling role on the cooling water inside a water jacket, so as to reduce the water flow entering the cylinder cover from a cylinder body. By means of the cylinder cover gasket throttling assembly, the size of the throttling hole on the throttling sheet can be adjusted according to the water jackets arranged at different parts of an engine. Accordingly, the cooling water capacities of all the water jackets are enabled to tend to be equal, so that the engine is cooled evenly. Meanwhile, the service life of the engine is prolonged. The utility model also discloses a cylinder cover gasket provided with the above cylinder cover gasket throttling assembly.
