Abstract

Patente de Invenção: <B>"BOMBA"<D>. Uma bomba hidráulica inclui um mecanismo de bomba (12) possuindo um eixo acionado (16). O eixo acionado (16) é conectado a um eixo de entrada (50) por um acoplamento flexível tal como uma conexão estriada. um alojamento (30) se estende completamente em torno do eixo acionado (16), e uma vedação de alta pressão (74) está disposta entre o alojamento (30) e o eixo de entrada (50). Um mancal de impulso (72) conduz as forças axiais hidráulicas no eixo de entrada (50) para o alojamento (30). Esta disposição fornece forças hidráulicas equilibradas em ambas as extremidades (18, 20) do eixo acionado (16), desse modo reduzindo a fricção e o desgaste.Invention Patent: <B> "PUMP" <D>. A hydraulic pump includes a pump mechanism (12) having a driven shaft (16). The driven shaft (16) is connected to an input shaft (50) by a flexible coupling such as a splined connection. a housing (30) extends completely around the driven shaft (16), and a high pressure seal (74) is arranged between the housing (30) and the inlet shaft (50). A thrust bearing (72) drives the hydraulic axial forces on the input shaft (50) to the housing (30). This arrangement provides balanced hydraulic forces at both ends (18, 20) of the driven shaft (16), thereby reducing friction and wear.
