摘要： A windshield repair device comprising a vacuum cup with a built-in piston and cylinder assembly is characterized by a transverse opening in the cylinder so that when the piston is partly withdrawn, gas bubbles can be drawn out of the repair liquid by the vacuum holding the cup in place against the glass. In operation, after the bubbles are removed from the liquid, the piston is moved toward the glass. The piston closes off fluid communication through the transverse opening in the cylinder and as it moves further toward the glass, it forces repair liquid into the damaged area. One end of the cylinder is provided with a sealing ring which bears against the face of the windshield to provide a seal. The cylinder is used as a reservoir for repair liquid, and allows gas bubbles to be removed from the liquid by the vacuum holding the cup in place. The piston has a pointed projection at its end which bears against a separated cone of glass in the damaged area and breaks the seal between the cylinder and the face of the windshield when pressure in the repair liquid approaches a level such that it is likely to cause permanent damage by delamination of the windshield.
摘要翻译：一种包括具有内置活塞和气缸组件的真空杯的挡风玻璃修复装置的特征在于气缸中的横向开口，使得当活塞部分地被抽出时，气泡可以通过真空吸入维修液中，保持杯子在玻璃上的位置。在操作中，在从液体中除去气泡之后，活塞向玻璃移动。活塞通过气缸中的横向开口封闭流体连通，并且当其进一步向玻璃移动时，其迫使修复液体进入损坏区域。气缸的一端设置有密封环，该密封环抵靠挡风玻璃的表面以提供密封。气缸用作修复液体的储存器，并且通过将杯保持在适当位置的真空使气泡从液体中除去。活塞在其端部具有尖端的突起，其在损坏的区域中抵靠分开的玻璃锥体，并且在维修液体中的压力接近可能导致的水平时，破坏气缸与挡风玻璃的表面之间的密封挡风玻璃分层永久性损坏。
