Abstract
A crimping machine for crimping a metal end fitting onto a flexible hose includes a stationary socket, a crimping die arranged in the socket for axial movement, and a hydraulic actuator. A valve member is provided in a fluid flow passage leading from a pump to the actuator. The distance between the valve member and a piston of the actuator is precisely controlled to control the axial movement of the crimping die relative to the socket.
