Abstract
A pressure cylinder, such as a master cylinder, primarily for use in a vehicle brake or clutch hydraulic system includes a cylinder component molded from plastics material, and an initially separate flange component which is preferably but not essentially, also molded from plastics material. The two components are provided with an interconnecting arrangement capable of transmitting axial thrust between the two components, and also resisting relative rotation therebetween.
Claims13
A pressure cylinder comprising:
- a cylinder component molded from plastics material;
- a separate body component surrounding said cylinder component;
- a plurality of first formations on said cylinder component;
- a plurality of second formations on said body component;
- said first and second formations being shaped and positioned on the respective components with respect to each other during and after assembly of said components so that during assembly said formations are interdigitated during relative axial displacement of said components in one direction to a position wherein relative axial displacement between said components in said one direction is resisted and said formations are relatively rotatable into substantial axial alignment of said first formations with said second formations for resisting relative axial movement of and sustaining axial loads on said components in a reverse direction;
- and
- locking means for locking said components when assembled against disassembly comprising an axially extending tongue removably insertable between adjacent pairs of aligned first and second formations and means integral with said tongue cooperating with a further formation on one of said components for positively locking said tongue in place.
