摘要： An impactor (10) having a fracturing portion (11) including a crank (12) and a force transferring structure (13). The force transferring structure (13) is hammered as a result of rotation of the crank (12) by a hammer (14) rotatably mounted to the crank for concurrent revolution about the crank axis (16) and rotation about a hammer axis (24). The hammer is rotated in synchronization with the crank to move a contacting portion (20) of the hammer reciprocatively toward and from the force transfer structure (13) with contact between the hammer and force transfer structure being free of rolling movement therebetween.

摘要： An improved ripper assembly (10) wherein a ripper shank (19) is mounted to the beam (11) of a tractor by a clevis pin (22) so as to minimize side forces acting on the shank pin (25). The vertical axis of the clevis pin may be aligned with the distal end (34) of the ripper tip (21) and the horizontal axis (24) of the shank pivot pin (25). The impact surfaces (28, 29) of the impacting mechanism (18) and shank (19) preferably define a plane of abutment in which lies a radius (30) from the horizontal shank pivot pin axis (24). This plane is further preferably accurately perpendicular to the ripper tip axis (31) extending perpendicularly to the radius (30). The arrangement provides a free pivoting action of the ripper assembly about the vertical axis of the clevis pin so as to effectively minimize side loads for improved extended life of the ripper assembly (10).

摘要： Une pompe a engrenage (10) possede une enceinte (12) definissant une premiere et une seconde cavites d'engrenages (38, 40) et un orifice d'entree et un orifice de sortie (42, 44). Une paire d'engrenages en prise (20, 22) ayant une pluralite de dents (32) et de racines de dents (36) est positionnee dans les cavites. Une paire de fentes de purge (50) sont prevues pour communiquer directement avec les racines des dents d'engrenage et permettre a l'air et au fluide entraines d'etre degagees des orifices d'entree et de sortie. De maniere avantageuse, les fentes de purge sont situees generalement adjacentes aux points de sortie (46) des cavites respectives, et une paire de fentes de charge (62) sont prevues pour faire communiquer la pression depuis l'orifice de sortie avec les dents d'engrenage et favoriser le mouvement de l'air entraine radialement vers l'interieur, vers les fentes de purge.

摘要： In reciprocating machinery, the force of the reciprocating mechanism on its actuator upon recoil often causes excessive wear on the actuator unless the recoil force can be damped. Such mechanisms requiring damping are used in rock breakers actuated by an eccentric. The damping device includes a recoil damper (10) for a reciprocating member (12) mounted in a housing (24) and includes an annular ring (38, 138) mounted adjacent a shoulder (28) formed on the reciprocating member, the annular ring (38, 138) being mounted in a viscous fluid interior of the housing. The annular ring (38, 138) cooperates with the shoulder (28) upon motion of the reciprocating member (12) in one direction and to restrict flow of the viscous fluid around the shoulder (28) upon motion of the reciprocating member (12) in the other opposite direction.
