摘要： A fluid power apparatus (10) includes a power piston (40) dividing a working chamber (18) from a first chamber (16), the power piston (40) biased toward a rest position by a spring (17) and the piston (40) displaced by means of restricting fluid flow between the working chamber (18) and first chamber (16). In order to keep contaminants from entering the first chamber (16), a collapsible filter (80) is disposed about a piston rod (13) of the power piston (40), the filter (80) having at an end cap (88) with a central opening (91) through which extends the piston rod (13) and at an opposite end member (98) a flange (95) which serves as a seat (97) for the spring (17). The end member (98) seats sealingly against the power piston (40) while the end cap (88) has a sealing mechanism (92) about the periphery of the central opening (91) to provide sealing between the end cap (88) and input rod (13). If during operation of the fluid power apparatus (10) the end cap (88) should engage an opposite wall (15) of the first chamber (16), the filter (80) collapses and permits continued full stroke displacement of the power piston (40) without damage to the filter (80). Should the filter (80) become clogged, the spring (17) seated upon the flange (95) permits the flange (95) to lift away from the power piston (40) so that fluid may bypass the filter (80) and effect continued operation of the fluid power apparatus (10).

摘要： The ball-and-socket assembly (10) comprises a rod (12) having a ball head (14) at one end thereof, the ball head (14) having a diametrical groove (16) with a flexible member (30) disposed therein and extending radially beyond the outer surface (14A) of the ball head (14). A body (44) includes a bore (46) having a flared entrance wall (50) communicating with an open end (48) of the bore (46), the flared entrance wall (50) extending axially inwardly to a radial shoulder (52) defined between end of the flared entrance wall (50) and a large diameter portion (54) of the bore (46), a small diameter portion (58) of the bore (46) being located axially inwardly of the bore (46) relative to the large diameter portion (54), and a frustoconical wall (56) extending between the small and large diameter portions (54, 58). The ball head (14) and flexible member (30) are located within the bore (46) such that the portion (30B) of the flexible member (30) extending beyond the surface (14A) of the ball head (14) is engageable with the shoulder (52) in order to capture the head (14) within the bore (46). Pivoting of the rod (12) relative to the bore (46) causes the flexible member (30) to move diametrically relative to the ball head (14) as a result of engagement with the frustoconical wall (56), and ensures that the ball head (14) remains trapped securely within the bore (46).

摘要： L'appareil d'entraînement hydraulique décrit (10) comprend un piston hydraulique (40) séparant une chambre de travail (18) d'une première chambre (16). Le piston hydraulique (40) est sollicité en position de repos par un ressort (17) et est amené à se dépalcer sous l'action d'un courant de fluide restreignant entre la chambre de travail (18) et la première chambre (16). Pour préserver la première chambre (16) des agents contaminants, un filtre repliable (80) est disposé autour d'une tige de piston (13) du piston hydraulique (40). Le filtre (80) comprend un chapeau d'extrémité (8) présentant une ouverture centrale (91), à travers laquelle s'étend la tige de piston (13) et un élément d'extrémité opposé (98) pourvu d'une bride (95) qui sert de siège (97) pour le ressort (17). L'élément d'extrémité (98) vient se plaquer contre le piston hydraulique (40), de façon à former une jointure étanche, tandis que le chapeau d'extrémité (88) comporte un mécanisme d'étanchéité (92) autour de la périphérie de l'ouverture centrale (91), pour assurer l'étanchéité entre le chapeau d'extrémité (88) et la tige de piston (13). Si, pendant le fonctionnement de l'appareil d'entraînement hydraulique (10), le chapeau d'extrémité (88) s'engage dans une paroi opposée (15) de la première chambre (16), le filtre (80) se replie et permet au piston hydraulique (40) d'effectuer des courses complètes sans interruption, sans endommagement du filtre (80). Au cas où le filtre (80) devait se boucher, le ressort (17) siégeant sur la bride (95) permet à la bride (95) de se soulever et, ce faisant, de s'écarter du piston hydraulique (40), afin que le fluide puisse contourner le filtre (80) et assurer un fonctionnement sans interruption de l'appareil d'entraînement hydraulique (10).
