DEVICE TO SWITCH LINEAR DRIVES TO MANUAL CONTROL Russian patent published in 2014 - IPC F16K31/50 F16K31/05 F16K31/14 

FIELD: machine building.

SUBSTANCE: proposed version of a device to switch to manual control comprises a manual control tool consisting of the first clutch on the first side and the second clutch on the second side opposite to the first side. The first driving member fitted by an external thread is connected to a drive case. The first driving member has the first end for detachable connection to the first clutch of the manual control tool, the second end - for selective connection to the drive's driving element, and a channel bored along the longitudinal axis of the first driving member. The second driving member is installed in the said channel to be coupled with the first driving member rotationally. The second driving member has the first end connected to the rod of the driving element by a thread connection, and the second end - for a detachable connection with the second clutch of the manual control tool. Rotation of the first driving member in the first rotation direction by means of the manual control tool moves the drive's driving element in the first linear direction, and rotation of the second driving member in respect to the first one in the first rotation direction by means of the manual control tool moves the driving element in the second linear direction opposite to the first linear direction.

EFFECT: improved design.
