Abstract

The invention discloses a venturi valve and a vacuum power assisting device, which relates to the technical field of automobiles, and aims for solving the technical problem in the prior art that people feel hard to stamp down a pedal when an automobile is braked as the vacuum degree inside a vacuum power assisting device is low. The venture valve comprises a suction tube, a venturi tube, a connecting tube body, an exhaust tube, a first check valve and at least one second check valve, wherein the air inlets of the first check valve and the second check valve are both communicated with the air outlet of the suction tube; the air outlet of the first check valve is communicated with the small-diameter port of the venturi tube; the air outlet of the second check valve and the air inlet of the exhaust tube are both communicated with the small-diameter port of the venturi tube through the connecting tube body. The vacuum power assisting device comprises a vacuum source, an air filter, a vacuum power assistor and the venturi valve provided by any technical scheme of the invention. The venturi valve is used for improving the vacuum degree of the vacuum power assisting device.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a Venturi valve which can be used in an automobile braking auxiliary system and a vacuum booster provided with the Venturi valve. Background technique [0002] With the rapid development of the automobile industry, car users have higher and higher requirements for car safety performance, and the vacuum booster device on the car has become an indispensable part of the car. [0003] In the prior art, the intake manifold is used to provide vacuum for the vacuum booster in the gasoline engine vehicle, and the intake manifold of the gasoline engine vehicle can generate a relatively high vacuum negative pressure and directly provide vacuum for the vacuum booster. The vacuum in the intake manifold comes from the suction process when the engine piston reciprocates. [0004] The rationality of the design of the vacuum booster device will directly affect the safety and reliability of ...
