F03B13/1845 - CPC Classification

Classification description:

Adaptations of machines or engines for special use; Combinations of machines or engines with driving or driven apparatus ; Power stations or aggregates characterised by using wave or tide energy using wave energy using the relative movement between a wave-operated member, and another member, where the other member, i.e. rem is fixed, at least at one point, with respect to the sea bed or shore and the wom slides relative to the rem
