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.

A centrifugal separator for separating contaminants from contaminated oil and which may be mounted in a variety of positions relative to an engine block is disclosed. The centrifugal separator has a shroud which defines a first chamber and has a hollow rotor rotatably mounted in the first chamber and defining a second chamber. Oil under pressure is admitted to the second chamber and flows into the first through tangential reaction nozzles in the rotor to cause contaminants to migrate toward the sidewall of the second chamber under the influence of centrifugal force. A jet pump is in fluid communication with the first chamber to prevent excess fluid buildup in the first chamber, which would inhibit rotation of the rotor. SU

A crimping machine for radially inwardly crimping an end fitting onto a hose by means of a contractible die assembly includes a reciprocable ram. A pusher assembly is mounted on the ram for transmitting ram force to the die assembly. The pusher assembly includes first and second semicircular pusher members, and the pusher members are mounted for axial movement with the ram and for lateral movement relative to the ram. The die assembly includes two disjuncted die sections, one of which is carried on the end of each pusher member by connecting means which permits relative radial movement between the die section and the pusher member. A cam follower on each pusher member follows a cam surface on the machine for moving the pushers laterally outwardly when the die sections are pulled from the socket by the pushers during retraction of the ram. During advancing movement of the ram, the cam surfaces close the pusher halves and the die sections carried on the pusher halves to form a die cavity in which the workpiece is located. Further advancing movement of the ram after the pushers and die sections come together forces the die sections into a conical socket to radially inwardly deform the workpiece.

A crimping machine for radially inwardly crimping an end fitting onto a hose by means of a contractible die assembly includes a reciprocable ram. A pusher assembly is mounted on the ram for transmitting ram force to the die assembly. The pusher assembly includes first and second semicircular pusher members, and each pusher member is mounted for axial movement with the ram and for lateral swinging movement relative to the ram about a pivot axis which is parallel to the longitudinal axis. The die assembly includes two disjuncted die sections, one of which is carried on the end of each pusher member by an attachment arm which is deflectable to permit radial movement of the die sections relative to the pusher members. The attachment arm is provided with manually deflectable tabs which secure the die sections in place during crimping and which are deflectable to permit removal and replacement of the die sections. The pusher members are opened and closed by a camming arrangement which includes cam rollers on each pusher member and a stationary cam surface having an arcuate lateral cross section to provide proper camming as the pusher members and cam followers swing about the pusher member pivot axis.
