1. A hose and pipe structure comprising:
- (a) an elongated tubular hose member having an outer surface, an inner surface, and a tubular axis;
the hose member having opposite ends;
(b) a pipe member with first and second ends and a circumferential groove on an outer surface of the pipe in spaced relationship to both the first and second ends of the pipe;
(c) the hose member including a radially outwardly projecting circumferential clamp guide to position a clamp on the hose member and formed on the outer surface of the hose member in axially spaced relation to an end of the hose member; and
(d) an inwardly projecting circumferential sealing rib formed on an inner surface of the hose member and positioned in axially inward relation to the clamp;
during use the rib being positioned directly beneath the clamp and within the groove so as to be located between the groove and the clamp;
the rib being sized and shaped to be received in the groove in the pipe so as to be adapted to seal about the pipe when pressure is applied to the rib by the clamp applying pressure axially directly from above the rib.

Abstract
A reinforced hose includes an inner layer, a reinforcing intermediate layer, and an outer layer. The inner layer has and inwardly projecting sealing rib extending circumferentially on an inner surface thereof. The inner surface may also have an end stop to be engaged by a fitting received in the hose. The outer layer has a pair of annular clamp guides projecting outwardly which are axially spaced from an end of the hose. The sealing rib is positioned between the clamp guides to indicate an optimum location for a hose clamp.

9. A hose, pipe, and clamp structure comprising:
-
(a) a pipe and an elongated flexible tubular hose member having an outer surface, an inner surface, and a tubular axis;
the hose member having opposite ends;
the pipe having an outer surface and first and second ends;
the pipe being received in the hose along the tubular axis and having an outer circumferential groove thereon spaced from both the first and second ends of the pipe;(b) a pair of radially outwardly projecting circumferential clamp guides formed on the outer surface of the hose member in axially spaced relation to one another and to an end of the hose member; (c) a clamp received between the clamp guides;
the hose member having an inwardly projecting circumferential sealing rib formed on the inner surface of the hose member in axially spaced relation to the clamp and being located directly beneath the clamp;
the sealing rib being received in the groove of the pipe during use and aligned such that the clamp is positioned radially directly above the sealing rib, so as to seal the sealing rib about the groove when the clamp is tightened against the sealing rib whereby the rib is received in the groove and seals therewith due to pressure applied by the clamp. - View Dependent Claims (10, 11, 12)

13. A high pressure diesel engine hose in combination with a pipe;
- the hose comprising;
(a) an elastomeric tubular inner layer with an inner surface, opposite ends and a tubular axis; (b) an intermediate reinforcement layer positioned in surrounding relation about the inner layer; (c) an elastomeric outer layer with an outer surface positioned in surrounding relation about the reinforcement layer; (d) a hose clamp; (e) a radially outwardly projecting and circumferentially extending clamp guide formed on the outer surface of the outer layer and operably positioning the clamp on the hose due to positioning of the clamp adjacent to the clamp guide; (f) a radially inwardly projecting and circumferentially extending sealing rib on the interior of the inner layer and extending radially inward from the inner layer; and (g) the pipe has first and second ends and a circumferential groove on the outside of the pipe spaced from both the first and second ends;
the rib being received during use in the groove;
the clamp being located directly above the rib and groove so that the rib seals with the groove when the clamp is positioned adjacent the clamp guide and tightened against the rib in the groove. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
