Abstract: In a gear pump or motor having a housing and at least two intermeshing gears, one of the gears being fixed to a rotatable shaft and the other being a shaftless gear having a plurality of gear teeth rotatable on a film of fluid in close proximity to an interior surface of the housing, the improvement being a unique tooth profile on the shaftless gear. Each gear tooth on the shaftless gear has a thick top land, preferably at least twice as thick as the top land on each gear tooth on the gear fixed to the rotatable shaft. This particular intermeshing gear tooth configuration increases the bearing surface of the shaftless gear on the film of fluid within the interior of the housing to better support the shaftless gear and thereby reduce frictional wear.

Abstract: A reduced impact piston assembly including a cylindrical body with a cavity formed therein and having a cross-bore formed therethrough which intersects the cavity. The cross-bore receives a piston pin which has an exposed intermediate portion aligned with the cavity for attachment of a connecting rod thereto. A wide groove is formed about the outer circumference of the cylindrical body which has its center aligned with the center of the cross-bore. Positioned within this groove are a pair of C-shaped inserts, the legs of which abut the ends of the piston pin to prevent axial movement of the pin within the cylindrical body. The C-shaped inserts cooperate with the pin to form a closed loop having a circumferential length which is larger than the circumferential length of the cylinder body. In addition, a portion of each of the C-shaped inserts is in constant contact with a cylinder wall. The C-shaped inserts are constructed of a material having a thermal expansion which is similar to the thermal expansion of the cylinder wall and less than the thermal expansion of the cylindrical body. These features cooperate together to insure that constant contact is maintained between the inserts and the cylinder wall at both cold and hot operating conditions thereby minimizing the presence of piston slap within the cylinders of an engine. The reduction of piston slap will minimize the noise of the engine and greatly reduce the amount of cavitation experienced on the outside of the cylinder wall.
Abstract translation: 一种减小冲击的活塞组件，其包括具有形成在其中的空腔的圆柱体，并且具有穿过其形成的与所述空腔相交的横孔。 十字孔接收活塞销，活塞销具有与空腔对准的暴露的中间部分，用于将连接杆附接到其上。 围绕圆筒体的外圆周形成宽槽，其中心与中心对准。 位于该凹槽内的是一对C形插入件，其一端与活塞销的端部抵接，以防止销在圆柱体内的轴向运动。 C形插入件与销配合以形成周向长度大于圆筒体周长的闭环。 此外，每个C形插入件的一部分与气缸壁恒定接触。 C形插入件由具有类似于气缸壁的热膨胀并小于圆柱体的热膨胀的热膨胀的材料构成。 这些特征配合在一起，以确保在冷和热操作条件下在插入件和气缸壁之间保持恒定的接触，从而最小化发动机气缸内的活塞撞击的存在。 活塞敲击的减少将使发动机的噪音最小化并大大减少气缸壁外部所经历的气穴量。

Abstract: A two-circuit cooling system for an internal combustion engine including first and second fluid circuits. The first fluid circuit includes a radiator and a liquid cooled heat source while the second circuit includes a radiator and an air-to-liquid heat exchanger. A fluid pump is connected across the two circuits and facilitates independent movement of the coolant through the two separate circuits. The pump accomplishes this by using an impeller member having multiple vanes on two opposite surfaces which are of different configuration and which are divided by a wall which cooperates with the housing to form two separate fluid chambers.

Abstract: A seal for an internal combustion engine having a fuel injection nozzle positioned within a stepped bore formed in a cylinder head. The fuel injection nozzle contains an exterior stepped configuration with a shoulder formed between its steps. The seal includes a ring circumferentially positioned around and contacting the smaller diameter portion of the fuel injection nozzle. The ring has a flat first end which abuts the shoulder of the fuel injection nozzle and a tapered second end which contacts the smaller diameter portion of the stepped bore. The taper is formed on an exterior surface of the ring and has a maximum outside diameter which is slightly larger than the smaller diameter portion of the stepped bore. The seal also contains an outwardly projecting bulge formed between the first and second ends. The bulge permits the first and second ends to move axially relative to one another as the fuel injection nozzle is axially adjusted within the cylinder head and during normal engine operation. The seal serves to prevent combustion gases, which are generated in the cylinder, from flowing into the larger diameter portion of the stepped bore.
Abstract translation: 一种用于内燃机的密封件，其具有位于形成在气缸盖中的台阶孔内的燃料喷嘴。 燃料喷射喷嘴包括在其台阶之间形成有肩部的外部阶梯构造。 密封件包括围绕燃料喷嘴的小直径部分周围定位的环。 环具有平坦的第一端，其邻接燃料喷嘴的肩部和与阶梯孔的较小直径部分接触的锥形第二端。 锥形形成在环的外表面上，并且具有比阶梯孔的较小直径部分略大的最大外径。 密封件还包括形成在第一和第二端之间的向外突出的凸起。 当燃料喷射喷嘴在气缸盖内轴向调节并且在正常发动机操作期间时，凸起允许第一端和第二端相对于彼此轴向移动。 密封件用于防止在气缸中产生的燃烧气体流入阶梯孔的较大直径部分。

The piston assembly includes a piston body having a concave configured cavity formed in one end and a plurality of recesses formed in its outer circumference. The piston body is connected to the crankshaft by a connecting rod having a spherical end which mates with the concave configured cavity. The connecting rod is secured to the piston body by an annular skirt which is attached to the piston body by a plurality of bolts. The bolts thread into retainers which are positioned in the recesses formed in the piston body.

Abstract: An interference fit cylinder liner is disclosed for use in an internal combustion engine. The cylinder liner comprises a long hollow cylindrical member open at both ends and having a smooth circular interior surface of uniform diameter. At one end of the cylindrical member is a deflectable thin wall portion having a circumferential convex cross-sectional outer contact surface. This thin wall portion is deflectable inward to form a tight seal with an inner surface of the cylinder head as the cylinder head is mounted to the cylinder block. This tight seal prevents the leakage of combustion gases from the combustion chamber to other parts of the engine.
