Beschreibung
Zusammenfassung:	The invention relates to a linear actuator comprising a cylinder portion 201 and a base portion 202. The cylinder portion comprises a housing 203 defining internally a compression chamber for containing a fluid and comprising a piston 204 assembly that can reciprocate within the compression chamber. The housing further defines a cylinder port (302, see fig. 3B) in fluid communication with said compression chamber. The base portion defines a first base port and a second base port and a passage extending therebetween fluidly communicating the first base port 208a with the second base port (301, see fig. 3A). The cylinder portion is releasably engageable with the base portion such that the cylinder portion and the base portion may be arranged in an engaged condition. The linear actuator may, when in an engaged condition, allow said cylinder port and said second base portion to be in fluid communication. The linear actuator may further comprise a valve means suitable for controlling the flow of fluid through said second base port.
