Abstract

The invention discloses a synchronous telescopic multi-stage cylinder with an auxiliary cylinder. The multi-stage cylinder comprises the auxiliary cylinder and a synchronous telescopic multi-stage cylinder body; the auxiliary cylinder is a pressure cylinder; one cavity of the auxiliary cylinder is communicated with a first-stage rod cavity of the synchronous telescopic multi-stage cylinder body; the other cavity of the auxiliary cylinder is communicated with a first-stage rodless cavity of the synchronous telescopic multi-stage cylinder body; and a rod cavity of a previous-stage pressure cylinder in the synchronous telescopic multi-stage cylinder body is communicated with a rodless cavity of a next-stage pressure cylinder.

Description

Technical field[0001]The present invention relates to the field of hydraulic art, and more particularly to a synchronous telescopic multi-level cylinder with a helper cylinder.Background technique[0002]In the field of hydraulic technology, the application of multi-level cylinders is very wide, but ordinary parallel multi-level cylinders are graded step-by-step stretching, and there is difficult to eliminate changing impacts, in some stability requirements, or synchronous requirements. Unable to meet the application requirements. The series-based synchronous telescopic multi-level cylinder level is a series relationship. At the time of exercise, it is simultaneously stretched, fundamentally eliminates the changing impact, making it easy to operate. However, the tandem synchronous telescopic multi-level cylinder is large due to structural relationships, and in the same trust, the cylinder diameter is much larger than that of ordinary parallel multi-level cylinders. Therefore, the appl...
