Volume ratio and capacity are controlled by slides which are rail guided. The slides are pressure-balanced, axillay and radially. The volume ratio slide has a piston balancing arrangement. The capacity slide has suction pressure acting equally on all sides thereof, consequently it requires no piston balancing.
