Abstract
Blowout preventers of the ram-type, each having a bonnet which is detachably connected to the preventer body, and which bonnet is movable away from the preventer body to expose the ram therewith for permitting removal of the ram from the preventer for replacement or repair, wherein the ram piston and cylinder which are operable for moving the ram to and from its open and closed positions when the bonnet is secured to the preventer body are also operable for moving the bonnet away from and towards the preventer body when the bonnet is disconnected from the body. Detent means are provided for resisting relative movement between the ram and the body when the ram is in the open position and the bonnet is disconnected from the body, whereby the bonnet can be moved away from the body to the exposed ram position and then returned to reengage the bonnet with the body. Flexible hydraulic fluid conductor means is provided for operating the piston and for moving the cylinder relative to the piston.
