wherein fluid flow through the first fluid passageway into the third fluid passageway actuates longitudinal travel of the operator and the door assembly away from body, and longitudinal travel of the actuating means towards the body; and wherein fluid flow through the second fluid passageway into the fourth fluid passageway actuates longitudinal travel of the operator and the door assembly towards the body, and longitudinal travel of the actuating means away from body.
a) a body forming intersecting horizontal and vertical passageways extending through the body forming first and second inlet ports for introducing hydraulic fluid to the body, the body having slide studs extending outwardly therefrom;
b) a pair of door assemblies, slidably mounted on the slide studs and capable of being releasably secured to the body, each door assembly having a longitudinal bore extending therethrough and further comprising:
a ram block, and means for actuating reciprocal movement of the ram block;
c) a telescoping hydraulic operator having a first dual-cylinder assembly telescopically connected with a second dual-cylinder assembly, wherein:
i. the first dual-cylinder assembly forms first and second hydraulic fluid passageways and has:
.cndot. a first end received by body, wherein the first fluid passageway communicates with the first fluid inlet port of the body, and the second fluid passageway communicates with the second fluid inlet port of the body, and .cndot. a second end engaged with an operator piston, and ii. the second dual-cylinder assembly third and fourth hydraulic fluid passageways and has:
.cndot. a first end threadably engaged with the door assembly, wherein third fluid passageway communicates with first fluid passageway and the fourth fluid passageway communicates with the second fluid passageway, and .cndot. a second end connected to a cylinder retainer;
d) an adapter, slidably received by the door assembly and abutted by the second dual-cylinder assembly, the adapter forming:
i. a plurality of hydraulic fluid channels communicated with the fourth fluid passageway, and ii. a longitudinal bore for receiving the first dual-cylinder assembly; and e) sealing means for reducing leakage from the fourth passageway;
