    摘要: A swinging blowout preventer head with fluid connector wherein the swinging head is pivotally connected to a blowout preventer body so that a hydraulic fluid system to the ram cylinder mounted with the head remains sealed off at all times, including during the swinging of the head to and from its open and closed positions. Such fluid connector is non-load bearing, and preferably is capable of lateral movement as well as arcuate movement to assure sealing abutment between the body and the swinging head in the closed position while still confining the hydraulic fluid in the fluid system.
