Abstract

Patente de Invenção: "êMBOLO DE COMPRESSOR E PROCESSO PARA A PRODUçãO DO êMBOLO DE COMPRESSOR". Um êmbolo oco tem uma parede de extremidade que recebe pressão em um diâmetro do cilindro de um compressor. Uma protuberância de reforço é formada na face de extremidade interna da parede de extremidade. O contorno da protuberância, da porção externa radialmente externa para a porção radialmente interna, primeiro se aproxima da face de extremidade externa e depois se afasta da face de extremidade externa. Portanto, o êmbolo é leve e forte.Invention Patent: "COMPRESSOR PUMP AND PROCESS FOR THE PRODUCTION OF COMPRESSOR PUMP". A hollow plunger has an end wall that receives pressure in a diameter of a compressor cylinder. A reinforcement protuberance is formed on the inner end face of the end wall. The outline of the protuberance, from the radially external outer portion to the radially inner portion, first approaches the outer edge face and then moves away from the outer edge face. Therefore, the plunger is light and strong.
