The invention relates to a scotch yoke fluid device (10). The scotch yoke fluid device (10) has a crank (11) with a big end having an axis (14) which orbits around a main axis (15) for the crank (11). Connecting means (13) are mounted on the big end axis (14). There is at least one piston (22) mounted for reciprocating motion in a cylinder (18) along a piston axis. The piston has a cross-sectional area perpendicular to the piston axis. The piston also has guide means (16) which include a linear surface transverse to the piston axis. The guide means (16) engage engagement means on the connecting means. There is at least one restricting means (24) for constraining the piston (22) to move along the piston axis. The restricting means (24), or a constraining means (19) for the restricting means (24), or both, always extend into a volume defined by the swept area of the crank (11), projected along the main axis (15) of the crank (11). The invention also provides components, such as pistons, piston rods, restraining means and constraining means, made of composite fibre. The composite fibre may include both aligned and non-aligned material. The invention also relates to methods of manufacturing such components.
