Abstract: A waste gate valve actuator is provided for use with a turbocharger having a flexible and durable thin non-fabric diaphragm substantially uniform in thickness comprised entirely of a thermoset or thermoplastic fluorocarbon material.

Abstract: A diaphragm for a turbo charger actuator includes a layer of fabric having upper and lower surfaces. A first layer of elastomeric material coats at least a portion of the upper surface of the fabric to prevent pressurized air from passing through. A second layer of elastomeric material coats at least a portion of the lower surface of the fabric to form a plurality of ribs thereon. The ribs reinforce the fabric and prevent dirt or other abrasive particles from wearing holes in the elastomeric material and the fabric. When the fabric has woven strands, the ribs protect some of the points where the strands intersect in key areas on the diaphragm.

Abstract: An actuator for a turbocharger includes a hollow body member having a open top. A flexible elastic diaphragm extends across and is sealingly secured to the open top of the hollow body member which sealingly secures it thereagainst. A cap covers the open top and has a recessed surface formed therein directed toward the open top. The cap is sealingly secured against the body member so as to define a pressurizable cavity in the hollow between the cap and the diaphragm, and the cap having a rigid stem protruding therefrom with a fluid passage extending through the stem and into fluid communication with the cavity. An actuator rod is axially movable by the diaphragm in response to a predetermined pressure in the cavity.

Abstract: An actuator for a turbocharger includes a piston axially movable within a housing. The piston has a plurality of annular grooves thereon, and a plurality of O-rings are loosely restrained respectively in the annular grooves. Thus, the O-rings are axially movable within the grooves prior to moving with respect to the housing, so as to reduce the hysteresis which normally accompanies movement of the piston within the housing.

Abstract: A combination valve for relieving pressure and vacuum conditions in a pressurizable tank includes an elongated rod with a spring seat thereon, a body member sealingly securable to the tank, a cover member secured for axial movement with the rod, a spring mounted between the body member and rod so as to yieldably urge the rod and cover member toward the body member, and an O-ring rollably disposed in a groove in the body member. The width of the O-ring is substantially less than the width of the groove such that the O-ring is rollable within the groove between the body member and the cover member. A seal member mounts on the rod and extends between the cavity and the cover member so as to normally sealingly engage the cover member and cover the vent. In a vacuum venting mode, the flexible seal member is suctioned away from the cover member and the vents therein in response to a predetermined vacuum present in the tank. The air can then be drawn into the tank through the vent.

Abstract: An actuator for a turbocharger includes a housing having a chamber therein, a piston assembly having a rod and a piston secured to a rod for axial movement therewith, a spring operatively interposed between the piston and the housing for urging the piston upward within the chamber. A hollow retainer is mounted to the housing and extends into the chamber alongside the piston. The retainer has a housed portion having a generally cupped shape with a cavity therein for receiving a pressure signal from the turbocharger. The retainer has axially spaced first and second peripheral protrusions thereon. An O-ring mounts on the retainer between the first and second protrusions and in engagement with the retainer and piston simultaneously. The O-ring rolls between the first and second protrusions in response to the pressure signal and the resulting relative axial movement between the retainer and piston, thus decreasing hysteresis in the actuator.

Abstract: An adjustable actuator for a waste gate exhaust valve of a turbocharger includes a housing having a first opening therein for communication with the pressure outlet of the turbocharger and a second opening therein remote from the first opening. The actuator also includes a rod interconnecting the housing and the waste gate exhaust valve through the second opening. The actuator further includes a pivotal mounting bracket connected to the housing adjacent the second opening. One or more flange portions extend radially outward from a central body portion which has an aperture therein for receiving the rod. The actuator also includes a fastener for selectively clamping the bracket to the housing such that the bracket can rotate and tilt with respect to housing when the fastener is loosened and is held in a fixed positioned once the fastener is tightened.

Abstract: A gas kettle-type barbecue grill is provided for use on boats or other environments. The grill includes a bowl-shaped base and bowl-shaped cover which are pivotally connected by hinges on opposite sides of the grill. Each hinge includes a pair of hinge arms having four pivot connections between the base and the cover. A burner is mounted in the bottom of the base, which horizontally receives a fuel inlet line. A flavor plate is mounted on top of the burner so as to evenly distribute heat within the base of the grill. The grill grate is secured within the base by mounting brackets. The grill is mounted to a post connected to a railing on the boat or to legs, and is rotable about a vertical axis so as to block the wind from the grate, regardless of the wind direction.

Abstract: Apparatus which can be installed over an opening on a container and can provide relief of excessive pressure conditions and excessive vacuum conditions in the container and provide rapid temperature actuated pressure relief for the container in the event of fire or other potentially dangerous heat related conditions, the apparatus including an aperture therethrough communicating with the container opening and a member releasable maintained in the aperture with a substance which melts at a predetermined temperature to enable pressure in the container acting against the releasable member to separate and even blow the releasable member from the apparatus and escape from the container through the aperture, the preferred construction including a self-actuating and self-modulating combined pressure and vacuum relief valve assembly which provides accurate pressure relief for the container at a predetermined over pressure condition and high inflow rates of air for vacuum relief at a predetermined excessive vacuum or

Abstract: A combination pressure and vacuum relief vent apparatus which accurately and reliably provides both high flow rates of pressure relief and negative pressure or vacuum relief in a container, the apparatus comprising a base member having a passageway extending between opposite ends thereof, one end of which base member can be mounted on or over an orifice on a container, a shaft member located in the passagway of the base member and a combination valve assembly mounted on the shaft member adjacent to the opposite or free end of the body member, which combination valve assembly opens to provide high flow rates of pressure relief at a precise predetermined first set pressure and closes when the pressure falls below substantially the same or a lower set value and which combination valve assembly includes a vacuum valve member which moves along the shaft member away from the combination valve assembly in response to the pressure in the container decreasing or falling below a second predetermined pressure condition

Abstract: A cyclic lubrication system is pulled by compressed air by way of a timer so that an injector manifold, having a plurality of injector valves, is fed with a lubricant which is gravity fed into the system during the off times of the cyclic air pulsation. Each of the injector valves is adjustable with respect to the quantity of lubricant delivered.
