Abstract:
1. A guide and retention assembly for spaced-apart plates comprising: a housing having a flange, a sleeve, and a bore through the flange and sleeve, the flange constructed for attachment to a first plate with the sleeve received in a hole in the first plate; at least one bushing received in the bore and located in the sleeve; and a rod slidably received in the bushing for axial reciprocation relative to the housing, a groove in the rod and adjacent one end of the rod, and the rod adjacent the one end is constructed for attachment to a second plate that confronts the first plate; a stop carried by the rod adjacent an other end of the rod, extending radially outward of the rod and engageable with the sleeve to limit axial movement of the rod in one direction relative to the housing; a wiper seal adjacent the flange end of the bore and bearing on the rod to prevent contaminants from entering the bore and the wiper seal can be received in the groove to releasably retain the rod in the housing and releasably limit axial movement of the rod relative to the housing in a direction opposite to the one direction; and another wiper seal carried by the sleeve and adjacent an end of the bore distal from the flange and bearing on the rod to prevent contaminants from entering the bore, and the stop is engageable with the another wiper seal to cushion further axial movement of the rod in the one direction relative to the housing.
