Crossover valve systems and corresponding methods offer an effective means to overcome large opening pressure force, or provide reasonable gas flow area, or both. In an exemplary embodiment, a crossover valve system for a split-cycle engine having a power cylinder and a crossover passage comprises first and second crossover valves, each valve opening outwardly away from the power cylinder and providing fluid communication between the power cylinder and the crossover passage, with the diameter of the second crossover valve being larger than the diameter of the first crossover valve; and an actuation mechanism operative to open the first crossover valve, then the second crossover valve after a predetermined delay to allow a certain rise in the pressure inside the power cylinder, resulting in much smaller differential pressure forces across the crossover valves, larger flow areas, or both.

A scanner unit is revolvable disposed to a recording unit. The recording unit and the scanner unit are coupled with each other with a damper unit including a holder, a rod, and a spring. The damper unit is disposed so that the operating direction of the spring switches in process of the opening and the closing of the scanner unit. A guiding surface capable of abutting on the projection disposed on the rod is provided in the recording unit. The projection abuts on the guiding surface before the operating direction of the spring switches in process of the movement of the scanner unit from its opened position to its closed position.

The invention discloses an adjustable panel valve which comprises a bottom plate. A through hole is formed in the bottom plate and a connecting sleeve is arranged on the bottom plate. A cover plate is arranged on the bottom plate. The upper end of the cover plate is fixedly connected with a pressing shaft which can be arranged inside a sleeve in a sliding mode. The portion, at the upper end of the pressing shaft, inside the sleeve is provided with a pressing ring. A spring is arranged between the pressing ring and the pressing shaft. The upper end of the pressing ring is provided with a pressing bolt connected with the sleeve in a threaded mode. A lever bar is connected with the position above the bottom plate in a rotating mode. The lever bar is arranged horizontally and fixedly connected with the sleeve. The adjustable panel valve is simple in structure, easy to realize, and convenient to maintain and clean. Moreover, opening and closing is carried out through rotation of the lever bar, opening force is reduced, difficulty during opening is lowered, the speed of opening is increased, the opening degree of the valve is adjusted and controlled through rotation of an angle, and operating is convenient and simple.
