Abstract

PATENTE DE INVENçãO "SAPATA SEMI-ESFéRICA". Uma sapata semi-esférica 1 tem uma supefície semi-esférica convexa 1A que está em contato deslizante com uma reentrância semi-esférica 2A formada num pistão 2. A superfície semi-esférica convexa 1A é definida por uma superficie convexa de um corpo giratório que é formado quando um arco de um círculo tendo um raio R2 e tendo um centro C deslocado com relação ao eixo L da sapata semi-esférica em sua direção ortogonal é girado sobre o eixo L como um centro de rotação. Uma entrada 1G, que está curvada em seção, é formada em direção à parte superior da superfície semi-esférica convexa 1A e mantém uma folga 7 com relação à reentrância semi-esférica 2A. O óleo lubrificante, que é armazenado no espaço 4 é fornecido de modo suave sobre a superfície deslizante 1F através da folga 7. A invenção proporciona uma sapata semi-esférica 1 que possui uma boa resposta deslizante e uma vida útil mais prolongada.
