CLAIMS
I claim:
A wave-to-hydraulic power converter, comprising:
two wave-engaging members connected by a hinge
which leaves said members free to oscillate relative
to each other about the axis of said hinge, wherein
said members assume always the same relative position
while at rest in the absence of waves,
a unit which by resisting changes to its length
absorbs energy, with one end of said changeable length pivotally connected to one of said wave-engaging members and the other end of said length pivotally connected to the other said member, and
wherein the axis of said energy-absorbing unit
defined by the points of its said pivotal connections, produced if necessary beyond the physical limits of said unit, substantially intersects said hinge axis when said wave-engaging members are in said relative position which they assume when at rest in the absence of waves.
The power converter recited in Claim 1, wherein said
wave-engaging members include a buoyant hull.
The power, converter recited in Claim 1, wherein said
energy-absorbing unit is a reciprocating force pump
having a cylinder and piston rod; the cylinder of
said force pump is pivotally connected to one of said
wave-engaging members, and the piston rod of said force pump is pivotally connected to the other said member.
The power converter recited in Claim 3, wherein said
wave-engaging members include a buoyant hull.
A wave-to-hydraulic power converter, comprising:
two wave-engaging members connected by a hinge
which leaves said members free to oscillate relative to each other about the axis of said hinge, wherein said
members assume always the same relative position while at rest in the absence of waves,
a unit which by resisting changes to its length
absorbs energy, with one end of said unit rigidly fixed to a first said wave-engaging member and the other end of said unit fixed to a crosshead slidably mounted in guides which are rigidly fixed to said first member,
a connecting rod with one end pivotally connected to said crosshead by a wrist pin and the other end pivotally connected to the second said wave-engaging member,
wherein the line of motion of said wrist pin, produced beyond the limits of said wrist pin's motion, substantially intersects said hinge axis, and
wherein the axis of said connecting rod, defined by the centers of said wrist pin and of said pivotal connection to said second wave-engaging member, lies substantially in the same plane with said line of motion of said wrist pin and with said hinge axis when said wave-engaging members are in said relative position which they assume when at rest in the absence of waves.
The power converter recited in Claim 5, wherein said wave-engaging members include a buoyant hull.
The power converter recited in Claim 5. wherein said energy-absorbing unit is a reciprocating force pump having a cylinder and piston rod; the cylinder of said force pump is connected rigidly to a first said wave-engaging member, and the piston rod of said force pump is connected rigidly to said crosshead.
The power converter recited in Claim 7, wherein said wave-engaging members include a buoyant hull.
