Cylinder assembly for fluid working machine

A cylinder assembly for a fluid-working machine, comprising:

• a cylinder body;
• a first valve having a first valve member;
• and
• a second, face-sealing annular valve having a second, annular valve member;
• the body having a first end and a second end and comprising a cylinder, a first valve seat and a second, face-sealing annular valve seat;
• the cylinder open to the first end and configured to receive a reciprocating piston;
• the first valve seat extending around a cylinder axis extending between the first and second ends and comprising one or more first valve apertures, the or each first valve aperture extending through the body and in communication with the cylinder and providing a fluid pathway through the body;
• the second, annular valve seat comprising at least one annular sealing surface and a plurality of apertures for an annular valve, each aperture associated with a said sealing surface;
• wherein the apertures of the second, annular valve seat are arranged around the cylinder axis and in communication with the cylinder, and provide a fluid pathway through the body;
• the first valve seat and the first valve member together forming the first valve;
• and
• the second, annular valve seat and the second, annular valve member together forming the second, face-sealing annular valve around the cylinder body.
