Abstract:
The invention relates to an insert (1) for a thermostatic expansion valve as a thermostatic expansion valve (2) comprising such an insert and to a method of assembling such a thermostatic expansion valve (2). The insert (1) comprises an expansion valve element (3) and an expansion valve seat (4). The expansion valve element (3) is held inside the insert (1) by a biasing member (5), wherein the insert (1) is structured and arranged to be inserted into a valve housing (8). The task of the invention is to provide an insert for a thermostatic expansion valve that allows a simple assembly of the valve and also provides an improved functionality. The task is solved in that the insert (1) further comprises a control valve (12), wherein the control valve (12) is located in the same flow path through the insert (1) as the expansion valve seat (4).
Abstract:
A servo valve (1) is provided comprising a housing (2) having an inlet (3) and an outlet (4), said inlet (3) and said outlet (4) having a common housing axis (5), a valve seat (6) located within said housing (2) between said inlet (3) and said outlet (4), and a valve element (8) movable relative to said valve seat. Such a servo valve should have a low pressure drop with limited costs. To this end said valve seat (6) is angled with respect to said housing axis (5) by an angle (α) in a range from 15° to 20°.
