凸轮轴调节器具有止回阀

Camshaft adjuster having a non-return valve
Abstract:
A camshaft adjustor (4), for an internal combustion engine (2), the camshaft adjustor having a stator (20), a rotor (22) which is rotatably accommodated in the stator (20), a pressure chamber (44) for adjusting the rotor (22) in relation to the stator (20) and a volume reservoir (70) for equalizing a negative pressure in the pressure chamber (44) via a channel (88) between the pressure chamber (44) and the volume reservoir (70). A non-return valve (72) having a closure part (102) for blocking a channel (88) which opens a volume reservoir (70) into a pressure chamber (44) in a camshaft adjustor (4), wherein the non-return valve (72) is formed of a metal sheet and the closure part (102) is realized so as to be movable in a recess (98) of the metal sheet (92) with two oppositely situated ends (94, 96) which are bent toward each other.
Abstract(Chinese):

一种用于内燃机（2）的凸轮轴调节器（4），具有定子（20）的凸轮轴调节器，可旋转地容纳在定子（20）中的转子（22），用于调节的压力室 相对于定子（20）的转子（22）和用于通过压力室（44）和容积储存器（44）之间的通道（88）均衡压力室（44）中的负压的容积储存器（70） 70）。 具有闭合部分（102）的止回阀（72），用于阻塞在凸轮轴调节器（4）中将容积储存器（70）打开到压力室（44）中的通道（88），其中不返回 阀（72）由金属片形成，并且闭合部分（102）被实现为可在金属片（92）的凹部（98）中移动，具有两个相对位置的端部（94,96），所述端部弯曲 朝向对方
