Embodiment 1
[0044] This embodiment provides a pressure wave generating device for cryogenic refrigerators and its assembly method. The pressure wave generating device adopts the double-sided diaphragm spring support mover technology to ensure the gap seal between the piston and the cylinder, and truly realize both. Frictionless movement improves the efficiency of the pressure wave generating device, thereby improving the performance of the cryogenic refrigerator.
[0045] The structure and assembly method of the pressure wave generating device will be described in detail below.
[0046] 1. The structure of the pressure wave generator
[0047] Such as figure 1 , Figure 8 with Figure 9 As shown, the pressure wave generating device includes a piston head 100, a front piston rod 200, a rear piston rod 300, a front base 400, a rear base 500, a leaf spring seat 600, a main base 700, a front diaphragm spring assembly 801, a rear Diaphragm spring assembly 802, motor assembly 900.
