Abstract: A cam-driven valve assembly includes a valve housing that defines a plurality of fluid passageways and supports an array of sliding-gate fluid valves in the fluid passageways to control the flow of fluid therethrough. The assembly includes a plurality of cams supported on a cam shaft. The cam shaft is arranged so that each cam is associated with a corresponding sliding-gate valve. Rotation of the cam shaft results in actuation of the valves via the cams. Each sliding-gate fluid valve has a movable plate that is connected to a cam via a leg that protrudes toward the cam shaft, the leg terminating in a cam follower that is mechanically connected to one of the cams. The leg is constrained to move within the plane by at least one of the guide teeth.

Abstract: A method performed by a first radio node The method is for controlling a transmission power level for transmitting one or more symbols in a channel to a second radio node in a wireless communications network. The first radio node obtains (901), for the respective one or more symbols, one or more transmission power parameters. The one or more transmission power parameters are related to the respective symbol type of the respective one or more symbols to be transmitted. The first radio node determines (903), based on the one or more transmission power parameters, a respective transmission power level to be used for transmitting the respective one or more symbols. The respective transmission power level is determined by taking an available power headroom in the first radio node into account. The first radio node then transmits (904) the one or more symbols with the determined respective transmission power level in the channel to the second radio node.
