FIELD: machine building.
SUBSTANCE: limiter is designed for unilateral mechanical action on the control object. It can be part of a purely mechanical emergency protection system. Working chamber is made in the housing. Volume of the working chamber depends on the position of the working piston. Working chamber is filled with bulk material. Bulk material has the ability to exit the working chamber only into the bulk material discharge chamber through the throttle opening. Bulk material discharge chamber contains a piston of the bulk material discharge chamber. Piston of the bulk material discharge chamber on the working chamber side is provided with an element. Pistons, the element and the throttle opening are coaxial. Cross-section of the throttle is blocked by the element either only in the standby mode, or in the standby mode and with the piston of the bulk material discharge chamber making part of its stroke. Circuit blocking the working piston in standby mode loses its blocking function when the expected emergency factor appears. Movement of the working piston is due to the natural exit of the bulk material from the working chamber to the bulk material discharge chamber without involving an external source of energy. Forces of interaction of several links of the blocking chain decrease.
EFFECT: reduction in overall dimensions.
