Abstract: A cylinder head of an engine is disclosed, the cylinder head including an upper deck, a lower deck, and a sidewall extending between the upper deck and the lower deck. The lower deck defines a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion. An engine is also disclosed that includes a cylinder block having a cylinder bore, and a piston slidably positioned within the cylinder bore. The engine also includes a cylinder head having a lower deck connected to the cylinder block, the lower deck defining a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion by a recess.

Abstract: A device for securing a towel includes a pair of opposed clamping members, adjoined at one end, free at the other end and defining an opening with a u- or v-shaped space therebetween. The opening of the space is preferably sufficiently wide to engage at least two layers of a towel. The clamping members are generally rigid but sufficiently flexible so that they may be deflected to increase the space therebetween. The inner surfaces of the clamping members include ribs to enhance gripping friction without snagging or damaging the towel. The face of the device provides space for an aesthetically pleasing design, logo or advertisement.

Abstract: A piston and connecting rod assembly includes a piston crown, a piston skirt, a connecting rod, and a bearing insert. The piston skirt is a component separate from the piston crown and is connected to the piston crown to provide a piston body. The bearing insert is a component separate from the piston crown and the piston skirt and is fixedly disposed within the piston body. A bearing surface of a connecting rod contacts the bearing insert to thereby movably associate the connecting rod and the piston body.

Abstract: A balancing mechanism for an engine that has a rotating crankshaft and reciprocating pistons such as those engines used in automobiles, aircrafts, boats, piston-driven compressors, piston-driven slider crank mechanisms, etc. The present balancing mechanism may comprise a first balance mass non-rotatably affixed to the crankshaft and a second balance mass rotatably supported on the crankshaft. A driver assembly is affixed to crankshaft to cause the second balance mass to rotate in a direction that is opposite to the direction in which the crank shaft is rotating. The driver assembly may include auxiliary gears configured to transport rotary power to auxiliary components.

Abstract: A guide for supporting sliding movement of a movable member includes a guide body having an outer surface, a first portion defining a first end of the guide body, and a second portion defining a second end of the guide body. A void is provided between the first and second ends and is defined by an inner surface of the guide body. A plurality of cooling projections project from the outer surface of the first portion, and a flange for stabilizing the guide projects radially from the guide body and defines a boundary between the guide's first and second portions. The guide may be adapted as, for example, a valve guide for use in an internal combustion engine for guiding the reciprocating sliding movement of a valve stem.

Abstract: A valve actuation device. The device may include a free floating valve bridge movably supported within a cavity in the engine housing. The bridge may be provided with a cavity and an orifice arrangement for pumping gases entrained with lubricating fluid toward the piston stems as the bridge reciprocates back and forth. The device may also include a rocker arm that has a U-shaped cross-sectional shape for receiving at least a portion of the valve bridge, valve stem valve spring and spring retainer therein. The rocker arm may be provided with lubrication passages for directing lubrication to the point wherein it is pivotally affixed to the engine housing.

Abstract: A fuel control system responsive to a power controller and controlling a fuel delivery system. The fuel control system includes a control arm connected to both the power controller and the fuel delivery system, a position sensor connected to the control arm, and a trim controller connected to the control arm at a pivot point and connected to the position sensor.

Abstract: A two speed gear box employs a planetary gear mechanism in which the planet carrier is in the form of a pinion gear which drives the second stage of the gear box. The gear box includes hydraulically actuated clutches which, in high gear, selectively lock the sun gear for rotation with the input shaft, and, in low gear, selectively lock the sun gear with respect to the housing so that the carrier pinion is driven at the speed with which the axes of the planet gears rotate about the sun gear. The annular gear includes an outwardly extending gear rack adapted to engage a generator driving mechanism. Pressurized fluid lubricant is provided to the generator housing and to the interior of the gear box housing. Expelled generator lubricant, still at relatively high pressure, powers an ejector to positively scavenge the fluid out of the gear box and return it to a cooling reservoir obviating the need for a separate scavenging pump.

Abstract: A turbocharger housing comprises a central housing portion having means for rotatably supporting the turbocharger shaft and a pair of end housing portions adapted to be bolted to the central housing portion at mating annular surfaces of each housing portion. In one advantageous form of the present invention, the end housing portions include a recessed wall for defining a flow passageway adjacent a radially expanded wall portion of the central housing, and a plurality of vanes are integrally formed on the end housing portion to extend outwardly from the recessed wall toward a mating annular surface on the central housing portion. One or more sets of radially spaced mating annular surfaces provides a secure engagement between the end housing portions and the central housing portion. Moreover, the end plates are removably secured to the central housing portion so that the turbocharger mechanism can be removed as a unit with the central housing portion.

Abstract: A turbocharger having a main housing with a throughbore in which a tubular bearing carrier is mounted. A main shaft having a turbine at one end and a compressor at its other end extends through the bearing carrier and is rotatably mounted to the housing by two spaced bearing assemblies. A lubrication system supplies lubricant to a squeeze film damper for hydrostatically damping the shaft vibrations and the discharge of the lubricant from the squeeze film damper is employed to lubricate the bearing assemblies.

Abstract: A turbocharger having a main housing with a throughbore through which a tubular bearing carrier is coaxially positioned. A shaft extends through the bearing carrier and is rotatably secured to the bearing carrier by a pair of axially spaced bearing assemblies, each having an inner race, an outer race and bearing elements entrapped therebetween. A pair of spacers are coaxially positioned around the shaft in between the bearing assemblies so that an outer axial end of each spacer abuts against the outer race of each bearing assembly. A helical compression spring in a state of compression urges the spacers axially away from each other to equalize the axial compressive load on each bearing assembly and thereby minimize bearing skidding and uneven wear.

Abstract: The present invention provided a balancing arrangement for an eight cylinder horizontally opposed internal combustion engine construction having a housing and a four throw crank shaft rotatably mounted within the housing. A pinion is coaxially attached to each axial end of the housing and includes a counterweight radially spaced from the axis of rotation of the crank shaft. At least one idler pinion is rotatably mounted to the housing and in mesh with each crank shaft pinion and each idler pinion includes a weighted portion radially spaced from its axis of rotation. Both the counter weights and the weighted portions of the idler pinions are angularly spaced from each other by a predetermined amount so that, during rotation of the crank shaft, the centrifugal force vectors of the crank shaft counterweight and idler pinion weighted portions cancel the primary moment generated by the piston reciprocation acting on axially spaced positions along the crank shaft.
