Title:
AN ACTUATOR WITH A PRESSURE RESISTANCE INCREASED DIAPHRAGM
Document Type and Number:
WIPO Patent Application WO/2019/040029
Kind Code:
A3
Abstract:
In an actuator (10) which, comprising a reservoir (20), a piston (40), a flange (60) that is secured to the reservoir (20) and guides said piston (40), and a wax (50) that causes pressure increasement in the reservoir (20) by expanding within it in a heat sensitive manner, transforms the heat change within a thermostat into a mechanical change; the present invention is a diaphragm (30) that mechanically actuates the piston (40) by flexing with the pressure exerted from the wax (50). For enhancing the pressure resistance of the region where the sealing is provided by compressing the diaphragm (30) between the reservoir (20) and the flange (60), the present diaphragm (30) includes a lip (32) structure that is formed by recess (31) and a protrusion between the reservoir contact surface (33) and the diaphragm's (30) outer surface in contact with the wax (50).
