Abstract

FIELD: hydraulics and pneumatics. SUBSTANCE: drive has housing with a connecting rod for supplying control pressure. The space of the housing is provided with piston and one or several flexible members. The flexible members are mounted on the support for permitting interaction with a bushing connected with the rod of a manual doubler and rod of an actuator. The support is provided with ports and ring. The ports receive projections made on the bushing. The ring is mounted with a spaced relation to the projections on the bushing. In addition the piston may be rigidly connected with the support and rod of the actuator. EFFECT: improved design.

Изобретение относится к пневматическим и гидравлическим приводам с ручным дублером. Привод содержит корпус со штуцером для подачи управляющего давления, в полости которого размещен поршень и один или несколько упругих элементов. Упругие элементы установлены на опоре с возможностью взаимодействия с втулкой, соединенной со штоком ручного дублера и штоком исполнительного органа. Отличительными особенностями является то, что опора имеет окна и кольцо. В окнах размещены выступы, выполненные на втулке. Кольцо установлено с зазором по отношению к выступам втулки. Кроме этого, поршень жестко связан с опорой и штоком исполнительного органа.The invention relates to pneumatic and hydraulic drives with a manual backup. The drive contains a housing with a fitting for supplying control pressure, in the cavity of which a piston and one or more elastic elements are placed. The elastic elements are mounted on a support with the possibility of interaction with a sleeve connected to the rod of the manual backup and the rod of the executive body. Distinctive features is that the support has windows and a ring. In the windows there are protrusions made on the sleeve. The ring is installed with a gap in relation to the protrusions of the sleeve. In addition, the piston is rigidly connected to the support and the rod of the actuator.
