  • Pneumohydraulic actuator
    Patent number: 5117633
    Abstract: A pneumatically driven hydrostatic actuator and a pneumatically driven recirculating hydraulic actuator are provided. Each of these actuators consists of a hydraulic pump fluidly coupled to an actuator. The pump is driven by a low inertia pneumatic motor that extracts pressure energy from pressurized gas and converts it to rotary motion. The pneumatic motor is preferably made from stainless steel A286 so that it can operate using pressurized hydrogen gas. The components of both actuators are in a closely coupled relationship so that they can be arranged in a compact unitary package.
