An exemplary door closer has an adjustable size and includes a rotatable member operable to adjust the size and an indicator mechanism configured to indicate the current size. The indicator mechanism includes a cover mounted to a housing of the door closer and a dial rotatably mounted to the cover. The dial is engaged with the rotatable member such that the dial rotates in response to rotation of the rotatable member. The cover includes an indicating region, and the dial includes a display surface including indicia relating to the sizes of the door closer. The display surface is non-perpendicular to the rotational axis of the rotatable member. When the door closer has been adjusted to a particular size, indicia relating to the particular size are indicated by the indicating region.

An exemplary door closer includes a housing defining a hydraulic chamber having a hydraulic fluid disposed therein. A pinion is rotatably mounted to the housing and extends into the hydraulic chamber. A piston is mounted for reciprocal movement within the housing, and defines a rack engaged with the pinion. The housing further defines an aperture in fluid communication with the hydraulic chamber. A regulating screw is rotatably mounted within the aperture such that rotation of the regulating screw in a first direction advances the regulating screw into the hydraulic chamber and such that rotation of the regulating screw in an opposite second direction withdraws the regulating screw away from the hydraulic chamber. A stop member is mounted in the aperture such that the stop member limits withdrawing movement of the regulating screw to thereby prevent leaking of the hydraulic fluid from the hydraulic chamber via the aperture.

An end member assembly can include a first end member section and a second end member section that together form an end member volume. A partition section is provided separately and is disposed within the end member volume to separate the end member volume into at least two volume portions. At least one passage extends through the partition section and at least one control device is disposed in fluid communication along the passage. The control device substantially fluidically isolates the two volume portions under conditions of use below a predetermined differential pressure threshold. The control device permits fluid communication between the two volume portions under conditions of use in which the predetermined pressure threshold is exceeded. Gas spring assemblies including such an end member assembly as well as suspension systems and methods of manufacture are also included.

A gas spring end member is dimensioned for securement along an associated suspension member having an associated planar surface and at least an associated first side surface. The gas spring end member can include a base wall disposed transverse to a longitudinal axis and a bracket wall that extends longitudinally-outwardly from the base wall. The bracket wall can be adapted for operative connection to the associated suspension member such that the gas spring end member can be supported thereon with the base wall disposed in longitudinally spaced-apart relation to the associated planar surface of the associated suspension member. A gas spring assembly including such an end member can be included. A suspension system and a method of installation including such a gas spring assembly can also be included.

A flexible sleeve dimensioned for securement to an associated end member for an associated gas spring assembly includes a flexible wall. An annular reinforcement member is embedded within the flexible wall. A retainment element that includes an element surface is disposed along the flexible wall such that at least the element surface is outwardly exposed. At least one gas spring piston, at least one gas spring assembly and at least one method are also included.

An end member for a gas spring assembly is dimensioned to receivingly engage an end of a flexible wall. The end member can be formed from polymeric material and can include a side wall receiving the end of the flexible wall. The end member can also include a base wall extending transverse to the side wall and dimensioned to abuttingly engage a jounce bumper of the gas spring assembly. The end member can include a mounting ridge or a mounting channel for engaging an associated structural component. A gas spring assembly including such an end member is also included.

A gas spring piston () includes an external retention feature () that is capable of receivably engaging and retention on an associated structural component (). The gas spring piston () includes an outer side wall (), a base wall dimensioned to abuttingly engage the associated structural component (), and at least one external retention feature () disposed along the base wall (). A gas spring assembly (), a suspension system, a gas spring piston kit, and a method are also included.

An end member assembly includes an end member body and an end member insert. The end member body can include an outer side wall, an inner side wall disposed radially inward relative to the outer side wall, and a bottom wall that together with the inner side wall at least partially define a cavity. The end member insert can be supported on the end member body and selectively rotatable relative thereto. A gas spring assembly and a suspension system are also included.
