  • Patent number: 7246636
    Abstract: A hydraulic fluid reservoir and hydraulic pump combination has at least one hydraulic fluid port and includes a container with a hollow body having a top and a conduit having a bottom within the container and a top above the bottom. The conduit has an opening adjacent to the bottom of the conduit. The opening is spaced apart below the top of the container. A closure member is releasably, sealingly connected to the top of the conduit. Hydraulic fluid can be added to the container via the conduit up to the level of the opening of the conduit. Addition of further hydraulic fluid fills the conduit to the top thereof and the conduit overflows if additional hydraulic fluid is added after the top of the conduit is reached by the fluid. Preferably the container has a main interior chamber and a smaller chamber which is adjacent to one of the side walls of the container. The smaller chamber is has a bottom opening near the bottom of the smaller chamber which communicates with the main interior chamber.

  • Patent number: 6213765
    Abstract: An orthodontic protraction appliance in which an upper portion of a vertically extending rod is supported against a patient's forehead, with the lower portion of the rod being supported against the patient's chest. An elastic support is coupled to a central portion of the rod to anchor a plurality of elastic bands connected to braces attached to the patient's teeth. In one embodiment, the elastic support is slidably positionable along and releasably fastenable to the first rod. An upper portion of a second rod can be coupled to a head band encircling the patient's head, with a lower portion of the second rod being coupled to the elastic support, which is slidably positionable along and releasably fastenable to the second rod. In such case, the elastic support is coupled to the central portion of the first rod to permit unimpeded vertical movement of the first rod with respect to the elastic support.

  • Patent number: 5427045
    Abstract: A power steering apparatus for a marine craft includes an actuator assembly including a hydraulic steering actuator. The steering actuator is operatively connected to the tiller of the craft. A hydraulic servo actuator is mounted on the steering actuator. The servo actuator is permitted limited axial displacement relative to the steering actuator. The servo actuator is operatively connected to the steering actuator. A servo valve is mounted on the actuator assembly and has ports for receiving pressurized hydraulic fluid. The servo valve is hydraulically connected to the steering actuator. A member operatively connects the servo valve to the servo actuator. Displacement of the servo actuator opens the valve to provide pressurized hydraulic fluid to the steering actuator. The steering actuator includes a steering cylinder, a piston reciprocatingly received in the cylinder, a piston rod connected to the piston and end fittings on each end of the cylinder.

  • Patent number: 5349818
    Abstract: A lock valve for marine hydraulic steering systems includes a valve body with a spool valve reciprocatingly received in a bore therein. A first port and a second port of the valve are connected to a manual pump. A third port and fourth port are connected to a double acting hydraulic cylinder connected to a rudder or steerable motor. There are valves within the lock valve which normally prevent fluid flowing between the ports so the steering system remains in a fixed position when the helm is released. Fluid can flow from the first port to the third port when the first port is pressurized. A return flow of fluid from the fourth port to the second port is permitted only when the first port is pressurized. When the second port is pressurized, fluid can flow the second port to the fourth port. A return flow of fluid from the third port to the first port is permitted only when the second port is pressurized.

  • Patent number: 5213527
    Abstract: An hydraulic actuator assembly for a power steering ram of a marine inboard/outboard drive of the type where the ram is connected to a tiller arm and has a spool valve mounted on the ram. The spool valve has a fastening tube which opens the spool valve when displaced in either direction to supply hydraulic fluid to the ram to move the tiller arm in the direction the fastening tube is displaced. The assembly includes an hydraulic actuator having a cylinder with an internal piston and a rod connected to the piston and sealingly extending from a first end of the cylinder. The rod has a distal end which connects to the tiller arm. The cylinder has a connector on a second end thereof. There is a mounting bracket extending generally radially from the cylinder which has a first end connected to the connector of the cylinder and a second end which is distal with respect to the cylinder. The second end has an aperture for connecting the bracket to the fastening tube of the spool valve.
