发明名称 Coiled tubing injector with flow limiter
摘要 A flow-limiting device is placed in a hydraulic fluid circuit between a hydraulic pump of, for example, a power pack, and a motor of a coiled tubing injector. The flow-limiting device allows hydraulic fluid to flow through the circuit, but limits the rate of flow in order to avoid thermal damage to the motor.
