FIELD: machine building.
SUBSTANCE: for accommodation of fuel pump in pipeline, lifting-and-downing mechanism with handwheel and spindle is used connected with fluid pump via threaded joint to allow the latter to slide along the spindle to pump fluid while changing fluid pump from working position into initial position is performed by converting rotation of handwheel with spindle into translation of fluid pump from working position into initial position by applying force to fluid pump lateral surface in direction opposite to direction of rotation of handwheel with spindle.
EFFECT: higher reliability, ease of operation.
