Abstract
A hydraulic ram including a stop system which defines a piston stroke. The stop system may be adjusted and the set position of the stop member may be coarsely read from graduation of a scale member while an adjustment ring has a finely graduated scale.
Claims14
A hydraulic ram comprising:
- a tubular cylinder having a head end and a bottom end;
- a piston slidably received in the tubular cylinder;
- a cylinder head secured to the head end of the tubular cylinder;
- a stop member threadably received in the piston and extending from the piston toward the cylinder head, wherein rotation of the stop member axially displaces the stop member relative to the piston;
- a counter stop member in the cylinder head disposed so that said counter stop member engages the stop member to limit travel of the piston toward the bottom of the cylinder;
- and
- an adjustment ring rotatably mounted on the cylinder head, wherein the adjustment ring is coupleable to the stop member so that rotation of the adjustment ring can rotate and axially position the stop member relative to the cylinder.
4 more elements
A hydraulic ram, comprising:
- a tubular cylinder,
- a piston slidably displaceable within said cylinder,
- a cylinder head connected to one end of said cylinder,
- a stop member screwed unto said piston and rotatable relative to said piston to thereby adjust a working stroke of said piston relative to said cylinder, and
- a counter stop member within said cylinder head, wherein an adjustment ring is rotatably mounted on said cylinder head in an axially fixed position, said adjustment ring being rotatably coupled to said stop member such that the latter is axially displaceable relative to said adjustment ring, and a scale being provided on said adjustment ring so as to enable reading of said stroke.
