Abstract A piston-cylinder unit having structure incorporated into the cylinder housing which will facilitate the connection of an end cap member without affecting the thickness of the sidewall construction of the cylinder housing. One end of the cylinder housing has a flared end, particularly a radially extending flange with one axially facing surface thereof forming a stop surface. The other axially facing surface forms a contact surface. The end cap member is composed of two parts, one part being the end cap itself with a central opening therein receiving the piston rod therethrough. The other part is a screw collar ring having internally threaded holes therein for receiving screws to effect a coupling of the end cap member thereto. The end cap member engages the stop surface and the screw collar ring engages the contact surface. A tightening of the screws will effect a clamping of the radial flange between the end cap member and the screw collar ring.
A piston-cylinder unit, comprising: an elongated and hollow housing having a central opening at one end and a laterally extending flange means at said one end thereof, said flange means consisting of a first portion integral with said housing and extending laterally from said housing and a second portion integral with said first portion extending coextensively parallel to said first portion but spaced axially therefrom, said first and second portions having a 180° angle bead portion therebetween; releasable end cap means secured to said housing at said one end thereof, said end cap means including an end cap member engaging a first axially facing surface on said first portion and covering said central opening in said hollow housing at said one end, said end cap means further including an annular collar engaging a second axially facing surface on said second portion, said first and second axially facing surfaces facing in opposite longitudinal directions; and fastener means for securing said end cap member to said annular collar and clamping said flange means therebetween.
