摘要： A cylinder assembly with split ring retainer having a hollow cylinder and a piston slidable therein and a rod extending from the cylinder. A cylinder head is attached to one end of the cylinder and surrounds the rod for supporting the rod. A split ring is disposed adjacent the piston and the cylinder head for respectively holding the piston onto the rod and for holding the cylinder head at its location with the end of the cylinder. The split ring and its cooperating adjacent part have inter-engaged tongue and groove inter-engagements for holding them together, and there is a member, such as a snap ring, for holding the split ring radially inwardly and against the part to which it is attached.

摘要： The means comprise a housing for a seal defined as a generally cup-shaped retainer, the wall of which is resiliently compressible in order that the retainer might be pressed into a cartridge or housing to retain a seal therewithin, in which the outer surface of the wall of the retainer has an annular lip which snaps into engagement with an annular groove formed therefor in the housing. The use of a plurality of the seal housing means, in stacked relationship, for sealing along a shaft or the like, provides an optimum spacing of the retained seals lengthwise of the shaft.

摘要： A one-piece piston rod wiping seal member for cleaning reciprocating piston rods or plungers as the rod moves into the cylinder chamber for cleaning dust and other foreign matter from the surface of the rod to prevent the foreign matter from entering the working chamber and contaminating the interior thereof. The wiping seal member is of one-piece construction and includes an endless body portion of elastomeric material with a pair of lips projecting axially and radially with respect to an end wall of the body member. One of the lips is a rod engaging lip and projects radially inwardly to engage the surface of a piston rod. The other lip is a cylinder end cap engaging the lip for engaging the end cap of the cylinder. The body portion can be snap fitted into a groove in the end cap of the cylinder. When installed, clearances are provided between the surfaces of the mounting groove of the end cap and the surface of the body portion of the seal member to prevent over stressing of the wiping lips upon lateral movement of the piston rod.

摘要： This disclosure describes a novel press-fitting fluidtight lubricant seal housing, an interlocking mounting bore, and novel lubricant and dust seals for use therein. The seal housing has an annular peripheral groove on the exterior sidewall, and the mounting bore has an annular peripheral projection or ring extending inwardly on the interior sidewall. The annular groove and projection interlock when the seal housing is telescoped into the mounting bore. An interior, cylindrical sidewall, connected to the exterior sidewall by a radially extending flange, has provision therein for retaining a dust seal element and an oil seal element. The oil seal has at least one seal lip at its inside peripheral portion extending axially inwardly. The dust seal lip is positioned adjacent the oil seal so as to form a pocket therebetween. The seal elements are made of separate pieces of elastomeric material.

摘要： A ROTARY SEAL COMPRISES A SHAFT ROTATABLY MOUNTED IN A HOLLOW HOUSING WHICH HAS A RECESSED PORTION. WITHIN THIS RECESS THERE IS A RING-SHAPED SEAT PORTION DISPOSED COAXIALLY WITH THE SHAFT. A STATIONARY BEARING SEAT MEMBER COMPRISING A SINTERED CARBON RING HAVING A FLAT BEARING SURFACE IS PRESSED AGAINST THE RING-SHAPED SEAT BY SPRING MEANS. THE SURFACE OF THE CARBON RING OPPOSITE THE FLAT BEARING SURFACE IS PREFERABLY IMPREGNATED WITH A MATERIAL SUCH AS A METAL TO AVOID POROSITY. HOWEVER THE IMPREGNATING MATERIAL DOES NOT REACH THE FLAT BEARING SURFACE. A ROTATABLE METAL SEALING RING MEMBER IS

PRESSED AGAINST THE SINTERED CARBON RING THUS PRODUCING A SEAL BETWEEN THESE MEMBERS.
