Beschreibung
Zusammenfassung:	A poppet assembly includes a poppet housing (41) having an axis and first and second sets of housing ports (41a, 41b), which are axially spaced. A poppet seat (44) is provided in the housing, the seat having a set of seat ports (44a), and a poppet (43) is also located in the housing and is retained by the seat. The poppet has a set of poppet ports (43a), is biased against the seat in a first position and can be moved to a second position away from the seat. A poppet actuator (45), which is located in the seat, partially surrounds the poppet and is biased away from the poppet. When the poppet is in its first position, the first set of housing ports (41b) are in fluid communication with the second set of housing ports (41a) through the poppet ports (43a), and when it is in its second position, the first set of housing ports (41b) are in fluid communication with the seat ports (44a).
