ABSTRACT:
In a timer device having a timer sleeve at a housing with a timer piston slidably provided at the timer sleeve, a high pressure chamber is constituted by securing to the housing a high pressure side cover member constituted as an integrated part of the timer sleeve. The high pressure chamber and a passage at the housing communicating with a chamber are connected to each other by a passage formed in high pressure side cover member. A check valve for absorbing shock waves generated within the high pressure chamber is provided in the passage in the high pressure side cover member. The passage can be designed and manufactured with ease, and at the same time, the timer piston and the check valve can be separately designed and manufactured. Furthermore, stable operation of the check valve is achieved.
